Well, I got my Treo 600 a little over a week ago, so I’ve been using it and getting to know all the features. I have to say that this is hands down, the best phone/PDA combo I’ve ever used. It is a triumph of industrial design.

I thought the loss of the cover would bother me, but have screen protector, will travel. And I certainly don’t miss the rocker on the side of the unit, which has been replaced with the awesome “four way” rocker, that allows you to just about everything short of typing with only one hand. Menu navigation, quick dialing, it’s all a snap.

The keyboard is smaller than the 300, but honestly, it’s still very usable for a chiclet keyboard. I can thumb almost 30 wpm. 🙂

There are some drawbacks, which are actually a little silly:

The camera has no flash

The screen isn’t high-res

Considering how much obvious thought and effort went into this design, to leave those two things out seems really stupid, actually. The are the only things stopping this from being a perfect combo for me. I’m not sure what they were thinking.

But overall, I love the thing, and would recommend upgrading to anyone with a 180/270/300… and if you are considering a cell phone/PDA combo, the Treo 600 is definitely one to take a very close look at.
