Vista is Okay
Okay, Okay!
People have been telling me over and over that my 'review' of Vista is not very true. Yes, Visat is the best version of Windows yet. (Not saying much) But, you really need at least 1GB of memory to run it on a PC. No I would not recommend upgrading, you need to buy a new PC. If the PC comes with Vista take advantage of the new features and security, but don't try to go through a lot of trouble just to get XP on it!
So, yes I would recommend Vista, if you are buying a new PC, I would not recommend upgrading.
