I don’t have any particular exotic hardware on my system, but Windows 7 still struggled to find drivers for basically everything. Screen resolution was limited to 640 x 480, and my external mouse didn’t work because apparently Windows 7 doesn’t have USB support. Bizarre. I’ll spare you the details of what I had to do to get the wireless working, but let’s just say it involved 27 hours of crying.
I own a Dell laptop, and I ***HATE*** the tech support service. Every time I need to talk to someone, I'm contacting a call centre in southeast Asia, and while I appreciate their efforts, they're not helpful. It's near impossible to talk sense to them.
