Computers that were once employed for business purposes at JPMorgan Chase and have reached their end of usefulness are not going to waste anymore, thanks to the the Tech Warehouse program.

Through Tech Warehouse, JPMorgan Chase and Good360 are providing non-profit organizations and schools with refurbished computers that are equipped with basic peripherals and OS software, allowing them to enhance their tech capabilities…. and their local communities.

Once a staple of any vacation, the postcard has since faded into obscurity due to the advent of technology and instant sharing. One company meshing the best of both worlds, Touchnote Ltd., has a popular app on both Android and iOS that allows users to turn photos into personalized postcards and have them sent for around a $1.49 per postcard. In celebration of the 2012 Olympic Games, both Touchnote and Samsung want users to have the luxury of sharing their amazing moments via a postcard without having to visit a local London gift shop. That’s why Samsung is sponsoring a promo that will allow users to send free Touchnote postcards up until August 31st.

If you thought that all apps that turn photos into “paintings” and “drawings” were total gimmicky junk, you’d be dead right. Applying a “find edges” filter and desaturating the result into grayscale doesn’t make a picture look like you drew it. It looks like you’re a dummy for even using it.

But things have changed: Glaze is an iPad app which actually makes faux paintings that look good.

Apple has just announced that OS X Mountain Lion is the most successful launch of Mac OS X ever, with over three million copies sold in four days.

“Just a year after the incredibly successful introduction of Lion, customers have downloaded Mountain Lion over three million times in just four days, making it our most successful release ever,” said Philip Schiller, Apple’s senior vice president of Worldwide Marketing.

Last year, Apple sold over 1 million copies of OS X Lion in the first day of release. It looks like Apple managed to not just match that rate, but exceed it with Mountain Lion.

Apple’s press release is after the jump. Have you updated to Mountain Lion yet?

Kicking off this week’s must-have apps roundup is a stunning new weather app called Solar, which boasts a simple, intuitive user interface and a no frills approach that doesn’t suffocate you with information you’re not interested in.

Instead of talking about something new here today, we thought it would be a good idea to do a little recap of some deals, freebies, and giveaways that, well, you should know about!

Like the iStack Bundle (extended through tonight!) or Website optimization ebook or the Retina MacBook Pro giveaway. More after the jump.

OS X 10.8 Mountain Lion has only been available for 48hours but that’s not preventing many Mac owners from already upgrading. The $20 price tag, combined with easy download access via the Mac App Store has led to an incredible rate of adoption by Mac owners across the globe, and it might be on pace to be one of the most quickly adopted operating systems ever.

A new traffic report released by Chitika this morning shows that more than 3% of Mac users surfing the web have already installed Mountain Lion. Estimates are claiming that about 2.11 million Mac users downloaded OS X 10.8 within the first 48 hours of its release.
