I really like Vista. I agree, 1 Gb is the minimum you should use with it. I have seen some of those underpowered $900 Dells, Sony and HP's try to run Vista with poor results. Usually adding some ram and removing most of the junk that is installed on those machines makes Vista run really well.
Remember when we went from DOS to Win 3.1? That 286 with 8 Mb of Ram suddenly would not run so well? That 486 did not seem so snappy when we went toWin 98. Vista does much more so it takes more resorces. A weak computer requires that you turn off some of the eye candy but there are may features in Vista that I very much like. I consider Xp, as good as it was in it;'s time, to be the downgrade.
I think that many of those who make a career of Vista bashing write their reviews and bashes on overpriced Apples and have a fanboi agenda. Some are just plain trols and some just don't want to learn anything new. They are all entitled to their opinion but this is mine.
