I also use CS4 and have had no problem saving files where I want. The filling system is much more sensible than vista and xp. I think probably you are one of these people that doesn't like change. If thats the case then by all means stay with XP but don't slag of something that you obviously don't understand (and probably doesn't want to either).
Windows 7 is the best thing since 98 - I suppose I do have an advantage in the I have used it since beta (as probley has most people on this forum) and then RC and then Microsoft gave me 7 ultimate for free :-D and I class myself as an experienced user (I know - self praise is no praise :-P).
By the way I installed XP on a clients laptop and SP3 after which there were 60 critical updates :-O
Anyway - you get on and use XP and those of us who want too will carry on and use 7.
