I imagine the 12" 3:2 form factor will remain. The 4's form factor is great.
What don't you like about it? I don't like the trackpad (and never have, possibly never will) but the keys are fine aside from being limited by their very size. A single button FN toggle might be my only wishlist item for the keys, not sure how else they could be improved without being too big. Also, if at all possible, a Trackpoint nipple mouse would be great but I dont' think it'd work on a flat device.
Oh right, I did that before when my desktop would randomly wake up...then when I got my new motherboard it stopped sleeping altogether. Sigh. Thanks, I'll check it out, sounds like it's chrome though. Canary fixed my gif problems with Chrome but it still locks up, uses too much CPU and has other problems. Firefox is looking more tempting. I hope Spartan doesn't suck, too.
