In taking a trip this summer via Amtrak and folding bicycle and I see that I will need internet access in order to check train schedules, find lodging and food while out on the bikes, and navigate in some of the larger cities and coutry areas we will be riding in. In addition, I would like to have my cell phone with me. It will be a 2 week "credit card" trip so we'll be packing very light (we can mail things to a few stops if necessary).

Even though it is compact my IPAD seems too heavy and will still take up more room in my backpack than I want. To do it all with what I have I would need to bring my cell phone (water proof), and IPAD (not waterproof) - with a data package, and possibly my GPS (waterproof).

So, I'm looking for something that will suit all needs. My guess is a Smartphone, but I really do not want to own one after the trip. I thought I'd purchase cell service/data package for the trip and then quit after the trip (I have WiFi at home and don't really need internet access everywhere).

Do any of you have suggestions on light weight, small-ish item that would fit the bill?
