6.5 months on and I’m still using Ubuntu as my operating system of choice. As you can see, I haven’t completely left Windows behind, but my Windows needs can be served inside a VMWare session.
I’ve upgraded to 7.10 and while I’ve lost a little of the Beryl eye candy, that’s more than made up for by the improved stability of compiz-fusion.
Would I recommend it to others? I guess that depends on your needs. Do you use Outlook? If so, stick with Windows because Evolution sucks, this is most especially true if you’re in an office that uses Exchange server. Do you rely on Photoshop or Paint Shop Pro? Again, stick with Windows because the Gimp will melt your brain. The most recent release is a vast improvement, but it is still a program designed by, and for people who would rather do their image editing on a command line.
Do you use Word or Excel? Then maybe you could switch to Linux. OpenOffice is much better these days, but MS Office is still a far superior suite. For un-demanding work, OpenOffice will satisfy your needs, but if you’re a Word or Excel power user, then forget Linux.
However, if your main use of your computer is for browsing, email and IM, then Linux will do the job.
