Yes, Dave, in the Paladin, the same mini-USB port is used as power and USB connection port.
The weak points of the Ainol tablet for now are: (1) weak wifi reception - can't be too far from the router; (2) limited apps (duh, the same complaint people say about Puppy Linux) - can't be worried there, as long as I have my browser and one office suite (at least 3 office suites are there to choose from); (3) some good software are not free, but costs 1 or 2 GBP only.
But I have used the iPad before, and it felt slow in loading the usual HTML pages, which isn't that pronounced in the Ainol. In fact, I can forget about looking for mobile-friendly webpages with this gadget. And its battery life in normal usage can last a work day - not bad, really.
About the reviews, the "garbage" verdict is too harsh, and this reminds me of the intense processor war for tablets going on, so we have to take tablet reviews with caution. :) And Linux hackers are now providing help and tweaks for the device - many are getting convinced of the Ainol's potential. The Google Market problems have been solved with the upgrade from Android 4.0.1 to 4.0.3.
And I stand corrected when I said that I still have to try Linux on it - Android is Linux, isn't it? But Linux for the MIPS exists. See Emdebian and MIPS developers.
Nooby, to update the Android on it, simply download update.zip to a mini-SD card, insert it, and power-on the device while holding Volume+. See this guide for details.
