A little birdie told me that the new iPad 3 will be out early next year, and I think I'll wait for that.
If you have a smartphone, and a data plan, it's easy to use the phone as the "modem" to get your wi-fi iPad online wihtout having to pay for a second data plan etc.
Maybe the new iPad will also have a USB port so you don't need to buy an extra gadget to plug your camera into.
