I'm playing with a Toughbook built in with an EvDO account from Verizon (I'll take pics tomorrow). This is a setup for my job, not for review... The Toughbook is overrated. It is heavy and bulky. I wouldn't want to lug one around.
The EvDO is awesome. Speeds of about 700kbps/60kbps. The upload sucks, but it is broadband speeds over the cell network. I'm impressed.
2014 is going to be a good year. More content, more streamlining. Be a part of history!
