Currently an M2 here. Our school recommends we get a PDA for 3rd year. The one they suggest is simply a PDA - not a phone. The 2 big things they "suggest" to look for in your selection is Windows Mobile and wifi. Now, like many people, I don't want to carry a cell and a PDA, so I was looking at smartphones. This is where I become clueless. If I get a smartphone through Verizon (my current carrier), I have to upgrade to a plan that is about $50 more a month even if the phone has wifi...I think. Now, if I get a PDA w/ wifi, do I have to pay any sort of company to allow me to get online? Or do I pretty much just pay the $400 up front and am good to go? If that is the case, it almost seems worth carrying 2 things around and not spending that extra $50 a month that I don't seem to have. Any advice? Anyone know why I have to pay that extra $50 if the phone is wifi capable?
