I just got this link from DeLorme:
Street Atlas USA PLUS - DeLorme
(click the above link to go!)
They have a bundle of their Street Atlas software AND (!) a GPS for $34.95. Use code 10013 during checkout.
I've used DeLorme software since version 1.0... and that was a LONG time ago. Their GPS dongles are pretty good. Combine this with a cheap netbook and you have one heck of an interactive road atlas. Remember that your phone-based GPS maps won't work when you are in the middle of nowhere. This takes care of that. Even though my current DeLorme GPS combo is working fine, I figure upgrading to the current generation won't hurt. And for 35 bucks? No-brainer.
