Anyone have an iPhone or come from one?

[eptd]

Stopped by the Apple store while I was at the mall yesterday and played around with the iPhone for a while. I know everyone here is an iPhone hater but I have to say I was very impressed. The touch screen much more responsive and internet pages are rendered a lot more quickly. And of course the screen is a lot more impressive (even with the lower resolution, can't beat size).

I know the plans are more expensive, can't customize as much, and blah blah blah. I'm wondering who has one or came from one has to say about the phone. I don't want to hear from people who have just played around with one or knows someone with one. I'm wondering what regrets I would have if I switched to the iPhone.

2 possible deal breakers for me would be Slingbox and Pushmail. I've seen a youtube video of the iphone slinging, but is this 'hack' readily available like custom ROMS are for the touch pros? And I'm guessing push mail is probably available but just wanted someone to confirm it.

What other regrets would I have?
