They are doing the same thing as they did when XP came out. Forcing people to upgrade by not creating drivers.
When I made my move to XP I had to bin my scanner as there was no XP driver and the manufacturer said they had no intention of creating one for older machines.
So I bought a new scanner. But I didn't buy from from the people who refused to create a new driver. I bought another make.
I do realise that its a rather large job to create drivers for a new operating system for all of your old products but I hope some of the motherboard manufacturers create their own drivers. I presume they are allowed to do this?
Anyway this is just another reason not to move to Vista now. Better to wait with your old dependable XP machine and in a few years time get a new PC.
