XP is probably the preferred version of windows. If all you are doing is checking email, writing documents and browsing the web and reading forums, then there isn't much reason to deal with Vista/7.
Oh no, Microsoft has had several operating system disasters, how can we forget Windows ME and Windows Vista....two fine OS's that defined stability, usability and reliability....not!
Not really, its just much more difficult to find one that works 100% since you can't swap out non-working parts. I recall reading some XPS laptops work great, bu i've not ever tried one myself.
