Well -- really -- my employer got me an iPhone ...

All in all I like it ...

Pros

Intuitive and clean interface
Does most things I want it to do. It makes calls. It plays mp3s. I can check Gmail on it. I can read Google Reader on it.
Seems stable (at least with a weeks "compliant" use -- see unlocking below)

Cons

If you are dialing up a number that is going to require you to enter a number afterwards (like an extension) you have to click the numberpad button AFTER dialing to get back there ...
Doesn't have a Flash plugin.

It won't allow you to install third party apps without "unlocking" it. This doesn't bother me that much. I am not planning on using a device that size in place of my laptop. It also has a built-in camera which I would be tempted to slam except that I used it to take 130+ pictures of a family visit to Afton Villa in St. Francisville. We forgot our regular digital camera. The photos are not great but they captured some moments that would have been lost otherwise.

I have managed to work around some of the clunky cons for my purposes (streaming audio, instant messaging) ... Meebo.com handles the instant messaging flawlessly. Orb.com allows me to stream content from a Windows machine which allows me to listen to my Yahoo Music content remotely. Its KIND of slow so I am not thrilled with the solution but one can say it DOES work. It sometimes misses small blocks of the songs. I may try the Orb 1.0 interface and see if that resolves the issue. I have heard people have had problems with 2.0. -- I know using a Windows middleman is not a true Mac die hard solution BUT I am not a Mac die hard. I am a realist that needs to use the iPhone.

Jott + Google Calendar + any phone - I am using this as my primary calendar because its real time. I do not have to sync my phone to keep it up to date. I make a phone call to Jott

Jott: "Who do you want to Jott?"
Me: "Google Calendar"
Jott: "Google Calendar. Is that correct?"
Me: "Yes"
Jott: (beep)
Me: "Call St. Francisville Chamber of Commerce at 9:30 am Wednesday"

Within three minutes it is on my schedule and usually spelled right (the example above is real). No sync required. In fact, I have removed all appointments on the Calendar application on the phone itself. I simply don't like it. Google Calendar has every option I need. I can sync with Outlook now using Google Calendar Sync.
