Apple needs to either shave the bezel off of the MacBook Air or forget the netbook category entirely.
Here's what they need:
13.3" MacTablet
Fully multitouch screen (Inkwell can do it easily, just create a larger system-wide gesture base that will expand and grow)
Air internals, same two setups (a larger HDD to start and a non-SSD upgrade added, though)
Slab format. None of this screen rotating crap.
$1,999 and $2,299.
Doesn't that sound Apple-y?
I think something more like the iPhone as touch screen. The multi touch with every trick borrowed or handed down by the iPhone technology.
Also, I'd say a 12.2" screen. Graphics same as the Air. To be over with it, the same internals as the Air go to this beauty.
I concur with the Slab setup with a hardware 'lock' button like that of the iPhone to prevent miss clicks/types.
Networking I will say full 802.11a/b/g/n-draft with WWAN integration to the User's preference.
Keyboard, well, this one will have to go like the iPhone virtual keyboard or a probable stylus integration in order to write out. Either one is fine, although iPhone virtual keyboard is more likely.
I/O ports, I'd say a Mini-Display, 1 USB, MagSafe, Audio in/out. Probably or maybe Ethernet and an extra USB.
I also guess the battery could go either soldered or user replaceable. Ram, may also go this way. HDD could also go this way. I mean, this may be a tablet, but just because of that doesn't mean it has to be thin like the Air, so the thickness of the tablet maybe same as the MacBook's.
Edit - Forgot to point out it might include a SuperDrive
