Yep, there's always going to be improvements.... considering that the moment the designers and engineers approve and send the model specs off for production the model is already obsolete. Trend analysts and we, the users, define what the next best thing is going to be with feedback.
If there was one thing I'd like to have, with an un-jailbroken phone, is the ability to tailor sounds for text messaging. It's there for phone function, but not for texts. Maybe it might be a simple firmware update....? I was surprised it wasn't there.
All in all the thing still blows me away- I've been into computers since the commodore. Evolution is amazing!
Cheers, Ted
