ostatic.com/blog: Now here is an open source (or at least partially open source) project that may have a strong chance of drawing legal action from Microsoft: ReactOS.
xenstreet.com: ReactOS is based on the earlier versions of Windows. Hence, it is not really directly competing with Vista or even XP. Hence, we wont be seeing it running on modern PCs anytime soon.
techpad.co.uk: I've just installed OpenSolaris 08.11, and I must say, it's really rather cool.
oneclicklinux.com: Microsoft has patented "pay as you go" PC computing. This means users could purchase low cost computers with usage based fees. A user would only pay for and use the specific software application needed. No thanks!
mac.blorge.com: We are documenting the move of a business user from the Windows platform on a PC to the OS X platform on a Mac. Why would such a user move to the Mac and not to Linux?
ditio.net: After reading a bunch of articles comparing Windows and Ubuntu. For me it seemed that, authors writing this articles never used Ubuntu they just installed because manager told them to compare this two operating systems.
aronzak.wordpress: A short while ago, I installed Windows XP on one of my computers. *horror*. It’s not so bad. It does some things quite well. Even after bloating it up with about 50 open source apps, it still seems to chug away quite merrily.
infoworld.com: The Mac's been on a roll, both due to its highly regarded Mac OS X Leopard operating system and to an unhappy reception for Microsoft's Windows Vista. The result: For the first time in memory, the Mac's market share has hit 9.1 percent, and Windows' market share has dipped below 90 percent. (Linux distributions make up the rest.)
AROS is an open source operating system that builds on AmigaOS. It can be run on powerpc and x86 hardware. It’s an independent, portable and free project, aiming at being compatible with AmigaOS 3.1 at the API level (like Wine, unlike UAE), while improving on it in many areas.
