The definition of exponential is “becoming more and more rapid”. I think you meant either:
“I think the increase in utility people will get from these capabilities will be exponential.”
or perhaps
“I think the level of utility people will get from these capabilities will be great.”

The bad news about the iPhone is that it’s a computer platform like no smartphone before it.

In other words, the point about supporting 2.x and 3.x is spot on. Many people who perhaps still didn’t “get” that the iPhone is a computer that makes calls could find out the hard way.

I think that’s why Apple made it clear developers should be testing their apps on 3.0 NOW. It was their way of saying “Hey, don’t just jump into the new stuff, make sure you’re existing stuff works too.”

It’s in the best interest of everyone in the iPhone ecosystem (not just Apple) that this first major release since the original SDK doesn’t “break” a bunch of apps. That’ll leave a bitter taste in consumers’ mouths and make for harder upgrades in the future.

I think having the option to buy extra levels for a game is awesome. Most of the times users will be happy with the included levels, but if the game is really cool you may want to extend the experience. This a great way to provide almost a “demo” of your app and if the app is successful then the user will want to get more out of it.

As for comments such as “Dog Machine’s” that’s what makes me and I bet many other developers really weary of putting any effort into developing for the platform. Developers write applications to earn a living, like any other line of work. Do you expect an electrician to come to your house and work for free? Never, plus you will be paying for his/her expertise. The same level of consideration and value should be applied to developers.

Anyway, I think 3.0 will allow developers to do some really cool stuff and I’m looking forward to seeing it.

I only wished Apple would also provide a better way for customers to manage their phones. There should be ways to manage your Springboard on the desktop and providing a better way to organize apps on the phone would also be really great.

dear iphone developers, if your app features this crap and its a good game, i will steal it instead of paying for it.
