There are far too many out-of-the-box bugs and glitches to consider this a usable product. For example, the convergence dock will not display on a monitor. Firefox browser displays too wide for the phone screen, so unusable. A dozen other issues on first day.
Even a development board should work better than this, have documentation of the known problems, and have some support mechanism that works.
I don't think better/more expensive hardware is the problem. It's software, caused by lack of users, lack of investment, and too many "competing" distributions of Linux.
