Laptop, Desktop, and maybe another Laptop. Also, given my experience with trying to get my Desktop de-authorized for Crysis: Warhead, I'd not trust Securom to give activations back (making it a one-shot game). Add into that the fact that I'll likely be changing hardware -GPU-, something that triggers a 'you have a new computer' message, in the Desktop and I'm just not willing to spend money for something that I'll likely be locked out of in the future.
