I had some few months ago made the switch. I had started using Ubuntu 7.04 Feisty Fawn back in early August. Come early September, I installed a then recent build of Gutsy Gibbon 7.10 and quite enjoyed it. Now that the official build has been released, I'll probably re-install for the heck of it.
Ubuntu is currently the most popular of all Linux distributions (according to its first place ranking on DistroWatch) thanks to its user friendly interface and Debian based core. Some of the new features in Ubuntu 7.10 are . . .
Ubuntu is quite the unique OS. But if you still require a Windows box to run some select few apps (3-D games not included), VMware Server and Vmware Player work exceptionally well with Ubuntu. I'm in fact running WinXP Pro inside Ubuntu right now and it is surprisingly smooth.
And as some may know, Dell has been selling select PC's with Ubuntu pre-installed.
"At its core, Ubuntu is a free platform for delivering open source software, certified and guaranteed to work, and with each release we strive to enhance the experience of our strong and growing user base of over 6 million people," said Canonical Chief Operating Officer Jane Silber in a statement.
In terms of what the future holds for Ubuntu, Gusty Gibbon 7.10 will be supported for the next 18 months. However, their next release of Ubuntu 8.04 (code named Hearty Heron) will have 3 years worth of long term support. Ubuntu also released new versions of Ubuntu Server, Kbuntu, Xubuntu and Edubuntu today
If you're interested, and I strongly suggest you try it if you've ever been curious about Linux, you can try the Ubuntu site (which is a tad slow right now due to all of the requests going on) or download from DistroWatch through HTTP or the better of Bit Torrent. There's tonnes of sources out there.
