We have Verizon, unlimited, about $80/month.

Initially we had problems with dropped connections -- they'd never admit it, but we suspect they would disconnect a data line before dropping a call if their "circuits" become over-crowded. (Our suspicions were based on the times when disconnections would occur.)

For the last year though, it's been great. (Though with my wife out of school now, we may decide to drop it if we find we're not using it enough.)

My brother has Sprint (unlimited too); he has no complaints about it. Over the Christmas holidays, we were comparing the Sprint and Verizon side-by-side -- including swapping cards between the laptops to compensate for differences in the computers; we really couldn't determine that there was much difference between the two systems in the location we were (Tampa, Fl).

I've considered dropping the cable internet and just keeping the wireless card, but that would create problems with access if the laptop and card weren't at home when someone wanted internet access.

If we replaced one of our mobile phones with one that let us use the phone for internet access for the computer, we might go completely wireless for all internet.

If you do decide to try wireless, I'd have the apartment/locations of use before getting the card. That way, if you find one of the locations you want to use it has a poor signal, you can return it immediately and (check your contract) most likely not be stuck with any cancellation fees.
