Where did you get that picture Schlud? I'm headed to the shelter now!
I got the jotto 5167 from Yourmobiledesk.com. The price is $147.99 plus probably $12 for shipping. Just buy an old laptop off eBay. I got mine for $300 and it works great. It's just a P233, but it has 96 MB of RAM, 24X CD, LAN card, modem, and was preloaded with good software. More than enough to run GPS and download photos to on the road. You can even buy laptops directly from Dell financial services on eBay for good prices; assuming you would want a Dell. That's what mine is (Dell Latitude CP233XT, I think), though I didn't get it from Dell. The ones through Dell are a little newer than mine.
Anyhow, here's a link to the Jotto Desk.
