Hey Scott,
As you know, I spend a lot of my life away from populated areas. I'm connected multiple ways to the Internet.
For temporary Internet connections, it is real hard to beat the Virgin Mobile cards. You can buy them at Wal-Mart and get 10 days or 30 days at at time. The 10 day card has data limits. I think it is $20. My 30 day card is unlimited and costs $40 per month. I can actually connect five computers to it wirelessly. On our recent trip to PB IV and Oklahoma, I didn't find any dead spots. When Lynda was driving, I was on-line. It works here at the bear den and at our house.
My other favorite is my Kindle from Amazon. It is not as versatile as a laptop, but there are no connection fees. It has incredible battery life. It works on the AT&T 3G network. The 3G Kindle, full-price, is $190. The browser is limited. The screen is black-and-white -- but the screen is big. You can't attach files to e-mails or to PB posts. You can't directly download PDF files, but it can read them. It has a built-in MP3 player. You can get unlimited books, magazines, and newspapers. For reading, browsing, checking Pond Boss, posting to Pond Boss without photos, and checking/sending e-mails without attachments, it is fantastic.
I hate my phone, but it works in a pinch for e-mail and browsing!
