Hi there, I decided to make an account here because I have a rather urgent question. I am doubting to buy an iPhone 4 or an iPad 2 (3G). I will basically MAINLY use the device for on the go stock trading. (In that view, I'll sign up for a dataplan with additional pay-per-minute call function.) It goes like this: I receive an e-mail of a new stock that's popped up on my custom watchlist. I want my device to power up OR make a sound (do whatever to catch my attention) so I can check my new e-mail and place the trade. I am sorry if this sounds a bit silly, but I'm not used to iDevices yet. Additionaly, I wonder if there are other people out there trading from their iPhone / iPad and which one they prefer. The size of the iPad is not an issue I think; it would even be nice to read ebooks on it. Price of any of the two is not an issue either.
