Since Amazon introduced its Kindle ebook reader, analysts and rivals have attempted to gauge its success via learning sales numbers. Because of that, the online bookseller has jealously guarded those figures – at least until Amazon CEO Jeff Bezos Thursday let slip “millions” of people own the device. That number is actually 3 million, according to a new report.

“The total number of all types of Kindles out there in users hands hit 3 million sometime in December,” Michael Arrington of TechCrunch writes, citing sources who’ve been “amazingly accurate” in the past.

Although Amazon spokespeople refuse to elaborate on Bezos’ “millions” remark, the word sent BusinessWeek to do some back-of-the-envelope calculations.

“Assuming that at least two million people have bought the device, and that each paid at least $259 – the cost of the least-expensive Kindle – Amazon now has a business worth more than $500 million in sales,” the publication said Thursday.

Citigroup analyst Mark Mahaney also figures Amazon could sell 2 million Kindles this year. Other analysts predict Apple’s iPad may sell twice that in 2010 alone.

Why is it so important how many Kindles is sold? Not only has Barnes & Noble’s Nook attempted to challenge the ebook leader, Amazon figured prominently in Apple’s introduction of its own “Kindle killer,” the iPad. CEO Steve Jobs announced his company will “stand on their [Amazon’s] shoulders and go a bit further.” In private, however, Apple has used Amazon’s pricing as a wedge to split off some big-name publishers. Although Amazon has attempted to adopt some of Apple’s practices (raising the royalties for publishers and adding apps to its e-reader), the company is squarely in Apple’s sights. Little wonder Amazon doesn’t want to talk numbers.

Guest commentary by David Barnard, owner of App Cubby, publisher of the popular Gas Cubby and Trip Cubby apps.

Much has been written about all the iPad surprises, disappointments, features, missing features, hype, expectations, future, etc. adnauseam. But not much has been written about what the iPad says about Apple. I’m excited about the iPad because of the many ways it demonstrates that Apple just gets it.

Palm almost gets it, Microsoft may be on it’s way to getting it with the Zune platform, Blackberry doesn’t have to get it, and Google just doesn’t get it.

What’s this “it” I’m referring to? Humans.

Enough of my dumb opinions. I thought it would be interesting to find out what some Mac and iPhone developers make of the iPad. What are their first impressions? What do they intend to make for the iPad platform? Do they have any concerns?

I got in touch with a whole bunch of developer contacts and asked them if they’d like to share their thoughts with you, the Cult readers.

Here are the replies I got.

Ken Case of OmniGroup revealed that the company is working on iPad versions of apps like OmniFocus and OmniGraffle:

“We’re really excited about Apple’s iPad, and are looking forward to updating OmniFocus to take advantage of the larger screen size. We’re also looking at creating iPad adaptations of several of our other productivity apps, such as OmniGraffle.”

Manton Reece of Riverfold Software (maker of Clipstart and Wii Transfer):

“I was so annoyed with the closed nature of the App Store that I stopped developing for the iPhone. The iPad will still have those frustrations, but the large screen opens up a whole new class of applications. It’s impossible to resist.”

Mark Bernstein of Eastgate Systems (maker of Tinderbox):

“The iPad announcement leaves many things unclear. Does iWork depend on private APIs, or will developers be able to write first-class applications? Will individual books be subject the the approval process — leaving 40 overworked Apple employees the additional task of approving or rejecting books an magazines?

“Since 1982, Eastgate’s been publishing original hypertext fiction and nonfiction. These works — many of which are now studied in universities throughout the world — can’t be printed and can’t be simulated in ePub. But, if we bring them to iPad, would that be vetoed as duplicating the built-in book functionality?

“In short, the app store is a source of grave concern for software developers. That said, the iPad is the most exciting personal computing development for a decade. It will transform our notion of computing and redefine the idea of the information appliance.”

Steve Jobs will never pitch a product more effectively than he did at the announcement of the iPhone. He said he was introducing three products: “A revolutionary phone, a widescreen iPod, and a break-through internet device. And they’re all one product: The iPhone.”

I thought back to that legendary pitch when I saw Steve affix one of his weakest lines ever to the iPad, a device I think actually has remarkable potential:

That’s right, the selling point is that it’s “Our most advanced technology in a magical & revolutionary device at an unbelievable price.” Really? Your selling points are advancement, magic, revolution, and cheapness? The best thing that line has going for is that device and price rhyme. First of all, almost no one buys magic. More importantly, Apple should never make price a central selling point; other companies can make cheaper knock-offs and then Apple has to re-convince people that that higher prices are justified. Once you try to become the price leader, you can’t really try to go premium again.

But the tagline was also a summation of the one problem that kept coming up for me as I watched the iPad announcement: the device simply does not have a killer app. A killer app, is the use that shows why a new technology is worth buying. For example, microwaves didn’t start selling until microwaveable popcorn was introduced and PCs didn’t sell until spreadsheet software was launched. The iPhone’s killer app, quite honestly, was Safari; the iPhone could certainly do a lot more than browse the web, but for many people, seeing the New York Times home page in multitouch made the sale.

The iPad? Well, I’ll say that the most impressive thing I saw today was the New York Times home page all over again. It’s even better than mobile web browsing than the iPhone. So what? That’s not enough to get me to spend $500. But not to worry. I believe the killer app for iPad is on the way, and possibly by launch. It’s called iLife.

Just a day after Apple’s announcement, we have the iPad topping our list of deals for Mac fans. The 16GB version of the thin, lightweight device is $499 and the 32GB version is $599. Next on tap is a number of MacBooks, starting at $599 for a 2GB model with 80GB hard drive and 2GB of RAM. Finally, if you’d like a MacBook Pro, there is a $799 price on a 2.16GHz version with a 15-inch screen.

Along the way, we also look at more hardware, speakers, software and apps for your iPhone or iPod. As always, the details are waiting for you on CoM’s “Daily Deals” page right after the jump.

With every new Apple product announcement, the press releases for third party accessories inevitably start rolling in. Here’s one of them, courtesy of bag maker Tom Bihn: a couple of iPad bags!

Neither’s particularly radical. The Cache costs 30 bucks is basically just a laptop sleeve rezised to fit the iPad’s dimensions.

The other is the Ristretto, a vertical messenger bag, which costs $120, and comes in olive, plum, black and cocoa.

Nothing too exciting here: these are just quickly redesigned iPad-specific versions of existing products. But, hey! At least you can get them shipped to you now in as little as one business day… unlike the iPad itself.

Yesterday, I speculated that the reason Apple didn’t put a camera in the iPad was to help you look thin, but as many commenters mentioned, another possibility is that Apple had another supply chain breakdown, like the one that robbed the iPod Touch of its camera in June.

Maybe that’s right. Techcrunch spotted that the iPad SDK has reference in the Contacts app to taking photos with a built-in camera.

There’s a few interpretations here. This could just be a legacy feature, having to do with the fact that the iPad runs on the iPhone OS. It could also have to do with the iPad’s ability to connect to external cameras through an accessory. Or maybe the camera was pulled at the last minute, just like the iPod Touch’s.

My guess is it’s a legacy goof. What do you think?

Although I was underwhelmed with the iPad overall — a natural reaction, I think, given how much my gig reporting on iPad rumors over the last couple months engorged my expectations — one thing I think the iPad did with its combo of a long battery life, great display and iBooks e-reading app was punch a steaming hole right through the chest of Amazon.

But I may have spoken too soon… at least as far as it concerns international iPad customers like myself. iBooks and eBooks aren’t even mentioned on the Australian iPad listing page. Other countries’ iPad pages feature similar omissions.

Now, obviously, this is simply an issue of getting deals inked with international publishers, but still, it’s troubling, and gives Amazon the leg up in at least one regard: after all, at least the Kindle’s e-reading functionality is now global, although it took them a couple years. I only hope we’re not looking at a similar 2 year delay for the iPad to do international e-books.

Maybe Terry McGraw III forgot the old World War II saying about loose lips. Not only can they sink ships, but prime exposure for your brand as well. It seems Apple CEO Steve Jobs didn’t like his iPad being unveiled by McGraw, CEO of textbook publisher McGraw-Hill on CNBC a day before the big event.

“Insiders say as soon as Terry shot his mouth off on CNBC, Jobs had the company cut from the presentation,” according to VentureBeat. Sure enough, Wednesday, when Jobs took the stage, McGraw-Hill’s logo was absent from a screen listing publishers involved in the iPad.

UPDATE: Check each contest website for details and closing dates — newer ones are last.

The contest list has doubled from the original post. If you hear of others, let us know. Scams have also cropped up with iPads as bait, so remember your due diligence.

Before the launch, we wrote about a daring intern who risked his job by staging a contest with the as yet unseen iPad as a prize.

Today,  a bunch of contests giving the iPad out as prizes have already cropped up, many involve no-brain activities like tweeting (sorry, witty chiruppers!) or signing up for Facebook groups. (If you can bug fix, try here or here. )

So if you want to get your hands on one without spending any cash, this may be the ticket.
