I'm a PC enthusiast and I can't get enough of Billy Gate's products. I've been playing around with Windows 7 since the first beta, much in the way that I did with Vista. I can see a huge leap between the two, in particular the way that the jumplists work and just how effortless it is to get something done without being pandered to by little UAC warnings or speech bubbles.
As a gamer, I want my OS to boot fast, launch the game fast (without any crashes due to crap drivers or broken .exe's), connect to the internet seamlessly in-game and just pretty much work. Windows 7 RC1 is doing that better than even XP did - I can't understand why people are hanging on to XP. Granted, I can understand people skipping Vista, which has been a bit of a farce tbh, but trust me, Windows 7 is leaps and bounds ahead.
Try it on a spare partition and see what you think, I imagine you will be pleasantly surprised.
Love because I think we need to spread the Windows 7 love!
