Hi All

Havent posted in a while, a friend of mine has recently aquired a new lappy and it came with Vista.
So far I havent actually had much of a look, except for a basic poke around in stores.

My question is, does it really matter if you buy an upgrade box?
or
should I go buy the full retail box.

My computer is in need for a bit of a reformat ( I try to do this every 8 months of so anyway )
I only have XP Home ( since I dont get too worried about OS, as long as its legal!)

The only disadvantage I can see is that I would have to install XP then upgrade to vista, which might be more time consuming?
Any comments of suggestions would be awesome
