I've been running this since day one on both my Surface Pro 2 and my Dell Inspiron 3147, and as contrary to fanboi opinion as it might be, I'm just not real impressed that this version is any kind of groundbreaking improvement for a touchscreen device. Sure, for a mouse and keyboard user...maybe it's a godsend, but if you've got a real touch-capable device...sorry, I'm just not feeling it. By the way, this latest build broke the autorotation on the Dell, so later this weekend I'm gonna have to troubleshoot that. I think it's some kind of issue with the STMicro gyroscope driver right now...
