Could need advise for a Convertible

Hi,

I'm planing to get a new tablet/laptop. Since I use it for some web development, only full Windows is an option.

The device should fulfill the following points:

  • 10+ hours battery life
  • tablet-mode (flip-around, detachable, doesn't matter)
  • fanless
  • baytrail (combines planed price point and battery life)
  • screensize: 10-12 inches
  • 1080p (or 1920x1200)
  • stylus
  • 3g enabled
  • ssd
Closest thing yet is the Dell Venue Pro 11, but this thing does come close, but it was announced ages ago and I', still waiting for a proper review...
Any ideas?
