we3 just purchased anew computer with vista on, yes there are some problems like some software we use wont work on vista and im not going out to buy new also my internet providers software hasnt fully installed as its not been brought up to date, there are also some things here that i like such as the side bar on the desktop i have a currency converter and a large clock ,notelets ,news block and weather for around the world also a calander these are not much bigger than icons but come in handy
i havent played with everything yet, i find that some webpages are small print though i have altered size
hope this gives you a idea to each to his own and all that

i would sugest going to computer shops and playing with a couple to see what you think
