Treo 650 for blogging in Europe?

I am planning a walking trip to Europe, and I want to blog my way around France and/or Spain. I would at least need email access, although web access could be an advantage. I figure I could write my blog as a memo on a PDA, and then just email it and have a friend post it, or perhaps paste it onto a blog website. Computer access is limited where I will be. Even finding an AC power outlet may be a problem, as I understand it. (Yes I know Europe is 220V, and I would need a plug adaptor).

I don't own a smartphone right now, and have no desire to pay hundreds of dollars for a phone for just one trip. The Treo 650 seems like it might be a good choice, an unlocked phone costs less than $100 on eBay, has a QWERTY keyboard, email, web access, PDA functions, camera, quad band, decent battery life. (I would probably buy a new battery before the trip).

What I want to do is buy a local SIM, and use a smartphone for local calls and email.

So I have a few questions:

If I buy a prepaid SIM, will I have data access? (I am thinking GPRS)

Will it cost me a lot to use data? What about sending photos?

What else do I need to know?

One concern that I have is that I may not have much if any chance to use/test/learn the phone before the trip, so I could easily imagine getting there and not being able to get email working, especially jetlagged. I stopped by AT&T, and they said for $70 a month I could get voice and data. (Since I would own the phone, no contract, just month to month). But $70 to learn to use a phone that might only cost $70 makes no sense to me.

Palm OS is the easiest to use and learn. You will not be disappointed. Get a Treo 650 as it will let you do all the stuff that you want, and more. The battery life is pretty good on the 650, it will easily last you 3-4 days with average phone usage and more than a week if you turn off the phone feature and only use the PDA.

Thanks. So far, the Treo 650 seems like a sound choice. I will probably wait until I have a firm departure date to buy one, since the price of used phones seems to drop every month.

I found out that AT&T Gophone has an unlimited data plan for $20/mo as a prepaid service, so I could go that way to learn the phone before I leave the USA.
