A) Apple may not get there first. Aside from polish and specific apps, I bet this wont be a whole lot different than the Touchbook (the version that sells without the keyboard).
B) If the Media Pad has the following, I'll probably be interested:
* 9" or 10" multi-touch screen, stylus optional (ie. can use one)
* Bluetooth and USB keyboard support
* "tether" to Mifi and Cradlepoint wifi devices
* tether to Bluetooth DUN, Bluetooth PAN, and USB devices
* if it doesn't have a physical keyboard, then it has to support both a full virtual keyboard AND full 80x24 ssh terminal on the screen at the same time.
* Apple remote desktop (both client and server), and preferrably VNC viewer as well.
* If it's not going to support desktop OS X apps, then it does at least have to support background apps, for things like allowing real IM clients to run in the background.
* A full IM client (multiple active IM personalities at once, multiple active IM protocols at once, AIM, Yahoo, MSN, Jabber required; IRC would be nice)
* Some form of firefox/mozilla browser (it can be the mobile version), in addition to Safari
* Compatibility with full versions (not just mobile versions) of Gmail, Google Reader, Google Talk, Google Docs, and Google Voice.
* It would be nice, but not required, that the device have a PCI-Express-Mini slot, or internal USB slot, that can be used with the 3G or 4G module of MY choice.
If it does all of that, I'll buy. If not, it'll probably be one of the last straw for me with Apple. I'll probably just continue on with my plans to see about Ubuntu-ARM or Mer on the Touchbook.
