Let the hive mind of Engadget get that for you.
"I just switched to Sprint from Verizon about three months ago for the Pre. Then I went for the Hero about a week ago. Now, I miss my hardware keyboard and am thinking about switching to the Moment. I am still able to switch back to Verizon if I want and get the Droid when it arrives. Should I just trade up to the Moment when it comes out, see if I like it, and if not switch to the Droid? Or something else entirely? Help!"
Anyway it's only good that there are projects like Moko's one in development. Big sized (10"+) tablet format seems very interesting for many activities (productivity, note-taking, sketching, control surfaces...) that could be crippled by Apple's signature restrained hardware feature sets and application policies.
For istance, the 10" Moko spec lists a pen digitizer sensor, alongside a bunch of of ports (2 usb, 1 usb otg, 1 sd slot), all things that Apple may not feel the need to include in their sleek future tablet.
This, coupled with the chance to distribute Android apps without a strict centralized approval process, could lead to many interesting specialized use cases.
