The iPad will change computing. I think a lot of people don't see it yet, but I've been wanting to have something like it already since 15 years ago. It can do so much of what I want to do when I'm traveling and hiking:
Communicate with family and friends through email and Facebook, draw and paint, write, keep a journal, keep up with my finances, navigate trails, cities and roads and train routes, find train, bus, and ferry schedules, keep a route log, translate and find foreign words, book rooms and flights, hold and organize my photos, write in my blog, read books, listen to podcast theater and radio, listen to music, record local recipes, watch movies and TV shows, find local outdoor stores and bicycle shops, get information on weather and local conditions, get information on tide charts, make Skype telephone calls (using "IM+ Talk"), have a knot reference, have a star chart, have an on-board photo editor, take HDR photos (with Pro HDR... really cool!) and stitch together panoramas, keep a record of my diabetes, have a bird reference, have a first aid reference, keep a calendar and todo list, scan documents and articles for reference (though that will need the iPad with a camera, which will most likely come out with version 2).
Doug, try iCabMobile for the browser. Very well thought out (iCab is an old Mac browser from Germany that is established and robust), with tabs. Mercury Browser is pretty good, too.
Ben, I haven't seen Quicken yet, but try PocketMoney. An old, established ledger. I think you can import to Quicken, but I'm not sure.
I'm going to grit my teeth and wait for version 2, when the software has its wrinkles ironed out, there's a camera (for webcamming), there are more full iPad apps available, and the price goes down.I don't really need a G3 enabled model, but I want GPS, so I might spring for that as long as it's possible not to have to buy the telephone plan. I don't need two cell phones!!!
