I'm actually posting from my phone right now while waiting ti pick my daughter up but its a pain typing on the tiny keys. If you want true mobile access then a wireless broadband card from any of the major providers will probably meet your needs. Since most are USB now you can use pretty much any laptop. The plans run $60 per month. Places like airports, book stores, Starbucks, etc typically charge for service and you can get a variety of plans from them or pay for a day pass as needed. I've used it at airports several times when I've had long waits and work to do that required access and its not too bad for very occasional use.
