I had a client who recently purchased a win 8 laptop. The windows update a couple of days later was incompatible with the installed sound drivers. The result was a bricked laptop.. well almost bricked.. I was finally able to get to a restore point, remove the sound drivers and get it running.
Another client purchased win 8 and is still waiting for drivers for his recently purchased printer..
as a rprevious poster so well stated, I also object to reqiring my brain for the OS
Oh, and if you go win 8, you really should fork over anotheer 200 bucks for a touch screen
