Motley Fool has some good news: despite selling off its PC unit to Chinese computer firm Lenovo, IBM still hasn't lost its soul. Apparently, IBM researchers have cooked up something called the SoulPad - "a way to carry a powerful, personalized virtual computer (in the form of a USB key or some other portable device) from one PC to the next. The virtual computer's "soul" ... needs no new software and can simply be popped in and uploaded to a new PC via a USB, iPod, MP3 player, or cell phone."

So what's the takeaway lesson? Jack Uldrich of Motley Fool explains:

"This suggests that the era of being able to walk up to any computer and personalize it is now very near. And, if this is true, then the future value of PCs will continue to drop as it becomes less important that you have a computer and more important that you can access one."
