Mine's a WiFi-only 16GB model that I've had since day one. It's a pleasure to use but it hasn't really become indispensable to me. The things it does really well are: - Cooking using recipes from the Web - Instapaper - Tumblr (reading, that is) - Watching ABC TV programs - Reading eBooks (I've only done Kindle stuff so far) - Catching up on missed TV shows via iTunes - Reading instruction/repair manuals from the Web while using/repairing stuff - WeatherBug - Reading Apple's developer documentation The things it doesn't do: - Flash video, audio, and games - Objective-C/Cocoa Development - Multitasking (but soon, probably iOS 4.2) If I weren't occasionally developing iPad apps I would consider selling it, simply because I probably have more useful things to be doing with $500.
