I am interested in fairly good performance and
features (including wireless and GPIO), which has influenced my selection here.

* I assume a 43% (1GHz/700MHz) increase with the overclocking mod.
Also interesting but don't include GPIO (one of my requirements):
| The PC-on-a-stick's are coming out fast and furious. TG Daily seems to be a good place to follow the action. | ||
