1) No voice dialing.

Have you really tried shitty voice dialling in a busy, noisy place? Or even in the comfort of your home? I wonder how many calls you make using your stylus or address book compared to voice? And BTW, how many buttons do you press, before the phone;s toy voice dialling brings up voice recognition?

2) No IM clients.

This I hope would be available in iPhone in an update soon. It already has IM like interface for SMS ...

3) No Outlook syncing.

It does synch Contacts etc from Outlook. Maybe more would be available soon. Thats the beauty of having a software enabled device and is more prominently applicable in *A Software Enabled Interface*.

4) No easily swappable battery.

At 6-8 hours a charge and 400-500 charges, that would be at least 3-4 years before my battery runs out.
And considering that I can carry my charger wherever I go, Do I even care?
