Soon we will only be able to imagine what life was like before iPhone.
I too have never had so much fun with a gadget. On my Motorala phone with T-Mobile I did not bother with a data plan because the handset and phone were not ideal for surfing the net. I mostly used text messaging because it was easier though it took forever to compose a message with the traditional keypad. I only had WAP access to the web, which was not all that great, even though I paid $4.99 a month and barely used it. Now, with the iPhone, I can easily check email, watch or listen to podcasts, surf the web, and check and post to various message boards.
Yesterday I used Safari on the iPhone to find out which pizza places were open. Then I was able to use the links to call them directly and then save the numbers to my contacts. This is where the iPhone really shines, IMHO.
Life is good.
