Revolutionary?: Yes, I think it is. The ease of use of the interface is great. I think some of the features of this device will push PDA use into the mainstream which is great. I especially look forward to copy-cats who will likely increase resolution of their device and include WiFi as a basic feature.

Good: The touch screen works as well or better than any I have used (and I have predominently used touch screen devices for the past few years). I currently carry the HTC Mogul running Windows Mobile. It's fast and responsive to input. The screen is great, but I even look forward to better resolution down the line. For example the Nokia 9300i (and earlier predecessors) have 800x200 which makes web browsing reasonable.

Bad: My only real "beef" with the device is that I have a very strong preference to buy devices with a replacible battery. Most folks buy a phone with a 2 year agreement. It has always been my experience that batterys (in general) need replacing once a year for reasonable duration use. Every phone I have ever used has needed a new battery after the first year. It's a sweet device, but I personally don't like to buy anything without a replacible battery-- although I do own an iPod and it has this problem too.

Dialing and Text: In find the virtual keyboard they include the best-in-class which is to say it's still not a device for everyone. Most folks prefer physical keys for dialing and really even for a keyboard. This is in part why the Treo's, Blackberry's etc. are so popular. Even my HTC has a slide out keyboard (which I almost never use), but still I'd prefer to have a real keyboard. Obviously you don't get the slick design without the touch-only interface so this is a trade off. This would not stop me from buying one.

Nay Sayers: I don't really understand the Apple-bashing crowd. Similarly, I am not a Microsoft hatter either. I acknowledge that each technology has its place and some work better than others depending on your needs or preferences. The only part of this "bashing" I do understand is when either Apple or Microsoft "strong-arm" you into their technology by crippling (intentionally or otherwise) interoperability. An example of this on the Apple side is their essentially closed iTunes music store and their proprietary AAC format. The example on the Microsoft side would be how say Outlook lacks features when used with anything but exchange on the back-end, even when those features are not inately sever specific.

More: There's probably more press on this device than any product I can think of, so it's easy to learn more. Would I buy one in general? Absolutely. Will I actually buy one? No, not for now. My carrier is Sprint, and I don't switch carriers just for a phone. I expect a CDMA version will eventually hit the scene, even if its two years out.

(Sprint I don't actually love Sprint, but they give me reasonably priced voice and unlimited data. For what I use, keeping the monthly cost reasonable is a primary criteria.)
