Likewise: because you use a feature does not mean everyone else does too or should use it as well. Everybody uses their iPhone differently but there are similarities. A lot of people in this thread are overreacting and I must say quite a lot are the stereotypical American: they have no knowledge whatsoever about other countries besides the USA. They're flat out wrong: the rest of the world is bigger than the USA. Apple has to satisfy an awful lot of users so they'll be looking at similarities worldwide. Somehow people seem to be forgetting this very important fact.
Other phones have had quite a lot of features the iPhone didn't or still doesn't have (configuring the blips and bleeps, bluetooth profiles, etc.). That's the way it is with the iPhone. After 4 years you'd think people would know this by now. It's not other users you have to convince, it's Apple, after all it's their OS. Quite a pointless discussion about the blips and bleeps if you ask me.
Yes, I'd like to set my own blips and bleeps for sms, calendar and mail, not just my ringtone. However, it's not in iOS 4.2 (nor in any previous version) which this thread is about...
Ontopic: I've seen reports about iOS 4.2 fixing the proximity issue and making the iPhone 3G faster. Those are even better than extra sms tones!
