Although this is just a concept, the Lifebook X2 designed by Park Hyun Jin, may be the solution to your Tablet and Netbook woes... Why settle for just one or the other when you can have a device that can transform into both with just a flip...!
...the Lifebook X2 concept has a tri-fold form that allows it to fold into a tablet, UMPC, or netbook. When folded, the thin little gadget would be easy to carry. In netbook mode, it has a QWERTY keyboard and a trackpad. If the bezels of the screen could be made as small as the renderings show, the gap would barely be noticeable.
