I won’t be using this. At all. For the very simple reason that my cellphone provider charges me an eye, an arm and a leg for data usage. And I’m too cheap to shell out the extra5$ a month a data plan would cost me.
There are people out there though, that have these plans and would benefit greatly from this new service from Yahoo! It’s simple and it’s useful. Go here, get some driving instructions and have them sent to your phone. Simple.
Alternatively, you could always print them.
