Many RVers are going to be talking about a new EVDO router called the CradlePoint CTR350... its very small size will be a major attraction since it will take up MUCH LESS space that any other router solution sold by 3gstore.
There are at least three 'gotchas' that RVers should be aware of with the 'CradlePoint Travel Router'.
The first is that (so far) it only works with USB or ExpressCard devices... NO PCMCIA cards (like KPC650 or AirCard 595).
Second, it does not allow computers to connect via ethernet cable. It ONLY allows WiFi connections.
Third, it only has an internal WiFi antenna, which means whatever WiFi range it has, thats all you can get, you can't get no more.
I wrote a full review of the CTR350 complete with pictures that show its tiny size. You'll find my review on EVDOinfo.com
For those of you familiar with the Kyocera KR1 router, here's a picture that shows the CradlePoint CTR350 sitting on top of a KR1, to show relative sizes:
