Glad you mentioned that. Another reason to not upgrade: ram is maxed out @ 2G. I'll probably be buying a new barebones kit in another year or two, and get Win7 oem/jim*.
Plus it hasn't reached end of life. I'm interested to see what MS will do when someone releases a show stopping virus. I wonder if they will refuse to patch it or if the pressure to do so will be to great. They may actually be wishing for that to happen to speed up the adoption of newer OS's.
I'm running the 10 Technical Review and it's no different than 8 with a hybrid start menu. Of course it's still early so lots could change before it's released I guess.
