GIGAOM ROADMAP, SAN FRANCISCO — Back in 2000, no one wanted to buy Apple’s products. Steve Jobs realized that potential customers needed to see and play with Apple’s offerings before they could be persuaded to buy them. So he launched a chain of retail stores in malls across the country. It was risky, but it paid off handsomely.

Now Tesla, the electric car maker run by Elon Musk, is trying to do the same thing. Instead of a traditional dealership, Tesla is building a chain of car showrooms right inside shopping malls.

To build out the chain, Tesla tapped George Blankenship, Apple’s former Vice President of Real Estate, who helped to roll out Steve Jobs’ mega-successful chain.

While many Apple fans and IT professionals that support iOS devices in the workplace are eagerly awaiting tomorrow’s Apple announcement, a group of Apple in the enterprise experts are meeting at MacSysAdmin 2012 – a conference for European IT professionals tasked with managing Macs and iOS devices in business, education, and other workplace settings. The annual conference traditionally posts videos of its sessions online for free (as does the Penn State MacAdmins Conference that was held in the U.S. this spring).

That isn’t the only major conference for Mac and iOS IT professionals, however. October brings two other major events (one of them free) and there are a number of excellent smaller events scheduled throughout the fall.

After the insanely fast sellout of tickets for Apple’s Worldwide Developers Conference, which kicks off in a couple of weeks, we profiled a range of other events for Mac and iOS developers and for IT professionals who support and/or manage Apple’s desktop and mobile platforms.

While these events are great for developers and IT pros, they focus on the underlying technologies of OS X and iOS more than on how companies and other organizations can implement and leverage Macs, iPhones, and iPads in various businesses and industries. For that, there’s the i.Business Expo, a series of events focused on using Apple technologies to both improve business workflows and for customer/client engagement.

Oh look: talks from smart ideas conference TED have arrived on iTunes U.

There are six themed courses covering things like Visual Arts, Climate Change, and Creative Problem Solving. Each one comprises a number of different TED talks that you can watch for free.

Remember when Apple’s 2011 Worldwide Developer Conference sold out in under 12 hours? With the suspicion that the same thing could happen in 2012, developers Anthony Herron and Aaron Wardle have created a website called WWDC Alerts.

The simple site allows anyone to sign up to receive a SMS message when Apple makes tickets for the 2012 event available for purchase.
