I assume you meant Address Book? I can't dial a number from Address Book directly on my iMac either, yet the app still seems to serve a perfectly legitimate purpose.
And with VOIP-over-3G now allowable in the iPhone SDK, seems you could make a call from your iPad after all.
I did mean address book. You have a good point but I'm still having issues in trying to come to a clear realization for why I might buy one.
It does everything my iPhone does but it doesn't make phone calls. So if I buy one I still have to carry around my iPhone + the iPad. The issue I have their is they do the same things for the most part.
It almost makes as much sense as driving both my cars to work every day.
and about the Voice over IP . Let's not jump ahead of ourselves, this product was just announced a little of 24 hours ago. There's still a lot of IFS and many months before the iPad may be remotely possible of making calls.
IF Apple really did agree with a few VOIP software entities to begin developing for this.
IF AT&T is going to be ok with it afterwards (even though they made a public statement giving it a thumbs up, what one says vs what one does .... )
even then , i have my doubts that Apple will allow any company ie, skype be able to make their App interface directly from the Address book to initiate a phone call through a 3rd party app.
