The HP Envy x2 is what I've been waiting for. It's a hybrid tablet PC running Windows 8 that attaches to a keyboard + battery combination to form a laptop that will undoubtedly have very long battery life. It's going to be powered by a Clover Trail processor and the tablet + keyboard combination is only going to weigh about 3 lbs. I also really appreciate the fact that the 11" screen is an IPS (In-Plane Switching technology) display.
Now, the big question is: What will it cost?
I also hope they make it with an illuminated keyboard. I've been spoiled by using devices that have keys that light up at night.
