Everyone at my work is getting Vista Ultimate for free (well sorda, gotta spend a few of my days off doing the training) as part of our training requirements, not a jump that I wanted to take yet but, its free. Now I just have to decide which system to put it on, or if I should just wait till xmas when I do a new system rebuild. Im not sure if its OEM, or retail as of yet, since the box isnt in my hand. If its OEM and I install it on my laptop I wouldnt have to worry about transfering the license. More ram and a C2D are in store for that, and a phone call to MS should fix any activation issues with that. That still leaves me with my longterm problem, since I mostly game and watch movies on my PC I see Vista being something that I will be required to have on my main rig at some time, where my laptop can get away with XP or Linux. Has anyone had issues with OEM Vista and activation on a full system upgrade? I dont want to install it on my main rig and find out Im SOL in 6 months when I upgrade...
