"For the last few days, Windows 7 is just about the only OS anyone has been talking about. I figured it was high time for us to share the love and take a look at some other interesting free, downloadable operating systems.
Here's a collection of 20 that are worth checking out. There are plenty more, so if you'd like to add your favorites, share them in the comments!
Fedora 10 (pictured) - One of the few live distros that didn't have any trouble with the hardware on my MSI Wind netbook. My acid test: can it properly suspend and wake? Yes - and it does it faster than Windows XP, Vista, or Windows 7. OpenSUSE and Ubuntu both failed to resume properly.
Damn Small Linux - I wouldn't feel right not listing Damn Small. It's pretty amazing what you can do with a whole OS that's not much bigger than most Windows antivirus applications. 50mb gets you Firefox, XMMS, VNCViewer, MS Office Viewer, and much more. It's also easily extendable through the MyDSL service or by using the apt command.
Linux Mint - While it's based on Ubuntu, Mint has some features that I think make it a bit more user-friendly. For starters, there are several easy ways to find and install new software including the dead simple Mint Software Portal. Find an app, click the install button, bada bing! "
