Hardly any of what you said was actually relevant in the Android vs. this thing debate. I used to own an Android with a micro-qwerty keyboard, I could connect a variety of such keyboards to my current touchscreen-only phone, it has wifi, GPS and a mic jack (which the device in question does not) it already supports any earpiece/mic going and has fairly decent speech to text. So why is the device that already has 90% of what you want impractical, and this device which has 10% of what you want is not?

Also, most people can achieve a higher WPM on Swype than T9. I know it's a little more frustrating and trickier to text blind, but it's also way faster.
