I do think Nokia is missing out on a huge accessory market. I would probably spend more time on the idea, but the 770 is such a small market due to Nokia's incompetence on marketing and finding a market for this device.

There are bluetooth thumb boards out there, but they're either too small at 3.5" long, or too long at 9-10" long. Something that could slide onto the 770 and either flip out like the Cingular 8125/T-Mobile MDA, or something I could carry with, and just slide onto the bottom of the 770 would be perfect for on the go stuff. Using the on screen keyboard, whether pen or thumb, just sucks after a while. This device, especially with OS 2006, is capable of so much more.

Wake up, Nokia.
