I'm not sure if you're reading Marty Cagan's excellent Silicon Valley Product Group newsletter, but if you're not, you should.

This great article on the iPhone is one example of why. I agree with everything Marty says -- particularly his point about focus groups being useful -- but I'm not sure I agree with his final comment:
I’m not sure about the positioning of this device primarily as a phone. The device is much more than a phone, in fact, I’d rate the fact that it’s a phone (and I consider it the very first truly good phone interface out there) as secondary. The device is much more of a complement to the personal computer. It’s a bit like bringing my Mac with me everywhere I go. Perhaps more importantly, it is also the first mobile device that I can imagine being the only computing device many people have.
It is true that the iPhone is more than a phone, but it needs to be a great phone first and foremost before it's going to win that valuable, and limited, pocket realestate. Personally I cannot imagine having *only* an iPhone -- as good as the keyboard and screen is, I have no doubt I can type faster on my laptop. The laptop is a foot scale device, suitable for foot scale tasks. The iPhone is an inch scale device, suitable for inch scale tasks. Both are important and useful, but both are also different.
