I'm absolutely LOVE my iPhone 4 and was thinking of buying an iPad 2. But what can I possibly do on it that I can't already do on my iPhone? I use my iPhone more than my desktop, I even pay my bills from my iphone. If the iPad had a USB port then I could see a definate difference! Am I missing something? Help!! I don't want to waste my money but if there's more to it then it would be worth it.
