If you don't want a cell phone..but want to be able to be connected via emails anywhere (not just via WiFi) then Peek may be an option for you.

I just found out about it and am looking at maybe getting one..thing is..it would be yet one more gadget to carry around....

Basically it's $15/month and the device is either $20 or $60. No contract as you pay as you go.

I kinda like that I can send and receive SMS messages as part of the unlimited emailing service..and send Tweets

It was Wired Magazine's Gear of the Year and they have it at..Costco
