Yeah, the Kinect improvements are pretty sweet. Heck, more than sweet, they're ridiculously awesome - totally ready for fitness games using the Kinect now. I've played a couple of Kinect games with a friend over at his house (couldn't justify the purchase myself) and saw a LOT of potential in it. Skype is also pretty awesome - a natural extension, of course, for a system that includes and requires a camera. My family has been deeply entrenched in Skype for YEARS, and since I got my Windows Phone they've got me using it with them as well. It's perfect to be able to set up in the living room and see them on the TV. Not that I ever hooked my laptop up with HDMI to the screen, but I imagine Kinect would work a lot better and be more fluid than that setup anyway.
I really enjoy seeing the speed of the system, and yes, snap mode is okay (not sure I'd use it much) but it shows multitasking is definitely present and THAT is what the Xbox has always needed. I also liked some of their UI improvements over the 360 (FINALLY the last thing you were doing is displayed as a tile front and center. About time). I do agree that Microsoft is a kick-*** company, but they definitely have some faults and I wouldn't necessarily give them every last dollar from my bank account
Careful with blind devotion though
