SplashTop, and now Xandros is looking to bring that concept to every laptop with Presto!, a new Linux distro that's said to boot in "seconds." The idea isn't so much to replace Windows as it is to supplement it -- you select between Windows and Presto at boot, you'll still have access to all your files, and you can even uninstall Presto from Add / Remove programs. Not a bad way to get your Linux feet wet, and Presto seems like it's pretty functional as well: Xandros already powers the Linux Eee PCs, and it sounds like Presto will run decently on similarly low-powered / older hardware. The stock install comes with Firefox, Skype, a media player and office suite, but Xandros is working on an app store, so you should have lots of other options soon. Sounds promising -- we'll see how it goes when the beta's released on March 16.
