Been using a iPad 2 for around 3 years now. Like Brogan I didn't think I needed it, more or less got it to see how usable it would be in my offline business. Turns out that it ended up being extremely useful for calendar events, customer list and invoice/estimates. It was so handy, my father (73 at the time) and business partner ended up getting one and uses it daily. He always says "Why did I wait so long to get one of these!".
