The day pass for wifi is $10? I think by 2011 (date set to be completed), a lot of people will be on mobile data plans and it won't really be worth it to pay for internet on a 30 min ride.

Good luck getting mobile data signals on BART -- it's difficult just to maintain a cell phone call. The value here is the consistency of the signal.

(Not that I think that $10 is reasonable for a day pass.)

Which line are you riding on? I take BART from Dublin/Pleasanton to New Montgomery every day and the only time I lose my signal is through the Lake Merrit tunnel and Transbay Tube.

I mainly commute between the city and Berkeley. The signal obviously goes dead in the transbay, but it's been pretty spotty in the above-ground parts, too.
