I also got in the beta. My use case is backwards compared to many: I have a gaming PC hooked directly to my TV. I use a wired 360 controller and have a wireless htpc keyboard for when I'm using it for media. My laptop is on the other side of the room at a computer desk.
My plan is to use the laptop (15" 1080p screen) when I want to play RTS and point and click adventures and such. I've also got a 19" 1440x900 monitor that I plan on trying hooked to the laptop. I just haven't had enough time to really dig in. I only did a quick wifi test over the weekend, and it didn't go well. I had lots of latency with severe spikes that made it unplayable. I don't have a good router though by any means so I'll be running a cable soon.
In my limited use, best feature so far: Not having to log in when I switch between computers.
