I think there is a few people jumping too conclusions. Sure the firmware video quality is lower compared to SG's firmware, and the the battery is slightly weak, but the camera is far from 'faulty'.
The fact of the matter is that the camera has been proven able to be of, 1. High video quality and 2. Stable with the small battery. My experiences with SG's and Cambox's firmwares, respectively, have proven this to be fact.
As long as people have bought their unit from Foxoffer, I am pretty confident that they have the same hardware revision as me and have a good product that is waiting to be improved by a suitable firmware. In fact, I am more than happy running Cambox's firmware on my unit -- it does the job for now.
And I believe no one has asked SG to develop for the TCL version.
As a DCT 'guinea pig' I am really happy I bought this camera, the flexibility to customize firmwares has been great -- I feel it'll be pretty impressive to see what the community comes up with. I'm currently looking at seeing whether I can modify the firmware, further that what AFT lets you. So far I believe I've learned the unit runs on a YAFFS file system and is written in c++. Would anyone have the Amberella SDK handy? or resources on the topic? (It's been a while since I've played with DSPs and microprocessors)
