It's cool to see more companies make solid cards. I remember when EVGA was what nearly everyone wanted to get for Nvidia cards... those days are long gone now!
For some reason my comment posted 3 times so I guess I'll say 3 different things: the high resolution screen seems really nice. Although probably lacking in native content compared to 1080P it sure is nice to be futureproof.
The concept of back buttons seems really interesting. Having never used the G2 I'm curious on how much it actually effects efficiency/ease of use, but an interesting idea regardless!
