The Shuttle mini XPC we've recently reviewed is available with both Windows XP and Windows Vista pre-installed. A quick look at the Dell website confirms that the world's largest PC seller is also offering customers a choice on most of its computers.

Now, we haven't seen any firm numbers on how many people are choosing which version. But it's something we'll be looking into. Personally, given the choice, I'd go for Vista every time, but from the letters we've seen from readers, it's clear that not everybody agrees with me.

So it's over to you: what are the best reasons to pick up a new PC with Windows XP on it, when it's the same price as a Vista device?
