I will get Vista sooner or later as I need to work it first hand to help anyone who has problems with it..
Maybe after SP1 is out...
.....I have 7 computers.
4 have Win98se on them. 2 are older laptops, 1 I use only for my quickbooks and 1 is my sons that got submerged in a flood and a friend brought it back to life. Its terribly slow and I get told about it by my son all the time.

The other 2 with Win98se on them are desktops, 1 is my main system I use faithfully everyday and am on now. I think Win98 was the most stable system ever. I hate to give it up. Eventually I will have to as I the board I think is dieing on me....lost my onboard audio recently. The other is my husbands who only uses it to play solitaire check the weather for hunting purposes and porn
I also have 3 other desktops...
1with XP Home, 1 with XP Pro and 1 with Vista Ultimate.
When I get a call from a customer I can go to one of the machines and walk them through any trouble they may be having. I give free phone support to all my customers.
So it is nice to have multiple OS to choice from when you need to
