Re:GSM all the way (Score 1)

GSM is probably the best standard of communication out there, BUT (and this is a big but), it is not nation wide (yet). GSM 1900 is limited right now for the USA. VoiceStream, Powertell, Pacific Bell (aswell as many others) are some. And alot currently do not offer analog service with any calling plan, so if your traveling nationwide these are NOT for you yet! In a few years I imagine that the US will have coverage like Europe does with GSM but it hasn't come to the US right now.

If you travel nationwide then you want a good digital service but I feel its important to also have analog capabilities.

Coverage on a perfect day....
Digital == 2-5 miles per tower
Analog == ~100 miles per tower

Big difference, wonder why my analog phone's batery dies so fast... :P
