I hate to say this, but in my personally opinion, people who are not computer experts will fail at using linux for desktop. I consider myself a pretty cool keyboard jokey and yet I was scared away eight times under various different distros from SuSE to Mandrake to Red Hat. If you want a good and cheap server platform, linux or BSD is the way to go. If you want a good desktop platform, windows xp is still king despite all of its flaws. With a bit of tweaking to prevent virus and spyware as well as using Norton Ghost to back up your harddrive, its a whole hell lot more stable then KDE version crap point crap.
My point is, Linux is for servers --period-- ... Maybe in a few years it'll mature to a consumer desktop level, but right now, its definately not there yet. I have a dual althlon mp 1.8ghz servers which run on Debian soomth as a baby's ass --but no way in hell would i ever get any serious work (i.e. im a international relations major so like a 50 page paper) done on O'crap Office or Abi-Crap ...
So, if you're a light user who only needs to type the occasional diddle and don't mind the hassle of having to go through console everytime your want to add or remove a program as well as dealing with the constant KDE crashing problem, the GO FOR IT. Otherwise, stick with windows. Or, better yet get OSX, the best of the the best as far as desktop publishing and office productivity is concerned in my opinion. I know after I got my powerbook w, I dont use anything else for typing and working on websites. Ok, that was a rant, sorry.
