Nope, I haven't used the iPhone for more than 30 seconds. I do use email constantly, but I work for a company which uses linux mail servers to provide webmail to thousands (millions?) of our customers. We also eat our own dogfood - almost nobody in the company uses outlook for anything, so I'm very used to and actually prefer a competent webmail implementation to just about anything else.
It's amazing to me that I can look back on outlook/exchange or any other dedicated email/calendar/contacts app and realize it's not nearly as 'vital' as everyone thinks it is.
I do have to ask, though, how does apple implement a multi-select interface and finger flick scrolling on the same screen simultaneously? Multi-touch?
