I don't think I've seen an instance when just the wi-fi locked up. It's possible but usually I see the cable modem or router lock up.
Plus how would it connect through the TDS? Through the pins? They're not all that reliable for charging the darn thing.
What they could do, which would be sort of cool and stealthy is have the TDS play dual roles, a charging base and an access point. If that were the case and they had somone like Cisco System do the design and OEM the hardware, this could be a good thing.
Alas we may never know!
Maybe once we can use it for a video preview?
Hmmm... maybe you're damn right... but for what are the 18 pins???
