I have no contract, prepay, and free low-speed cell data. For this I pay about $10/month ( on average ). The speeds on the data sucks, but for the few times a month I'm not in range of a usable WiFi and desperately need to check wikipedia it does just fine.

I own a Mac and it's an open platform. I can download Xcode and develop applications without Apple's permission. I could install Linux on it, but why? The iPhone/Touch platform is a significant departure from their other platforms in terms of openness.

The iPhone is a wonderful device, it's the perfect example of function and elegance, but it's frigging expensive. It's far more expensive than I'm willing to pay for what is, in essence, a toy since I have no real need for many of the features.

Sure I could buy a touch, but that won't pair with my BT DUN for cell data when I need it. I also feel like the touch is the "red headed stepchild" in the Mac family being the only one where you need to pay for basic software updates. You can bet they will continue to handicap the Touch to make sure it's never a real competitor to the iPhone.

The n810 has really filled my needs without another contract or monthly fee. Having played with the 770 I have also seen incredible evolution in the software for the device. I'm also planning on feeding back enhancements to the community as I find them ( and there are so many to find ).

The SDK is a disappointment, in my opinion, it's far too restrictive to allow real interesting development. Sure it will be great for games and basic productivity apps, but Apple still can't even make their flagship Safari stable on the platform.
