How would you change Sprint's Epic 4G?

It's the only Galaxy S variant to offer 4G connectivity, but it's also the only one that requires a $10/month data surcharge to use. That boost in cost will undoubtedly bring higher expectations, and we're eager to hear from early adopters on how their Epic 4G experience has been. For those who skipped over the EVO 4G in order to get this, we're keenly interested to find out if you've been satisfied with the decision. How's that slide-out QWERTY keyboard treating you? Would you have changed up the UI any? Would you have added any of the quirks from those other Galaxy S versions to this guy? Speak loudly in comments below. But not too loudly. More like a stern whisper.
