The G1 is great. It's about as tall as the iPhone, not as wide, but almost twice as thick. The reason for its thickness is a full hardware keyboard that slides out from underneath the screen. Most phones with large screens tend to have software keyboards: they are programs running on the screen covering up part of whatever application you're using. While I've never tried an iPhone, I had an iPod Touch (which I've since given to Holly) and tried using the SSH client on the iPhone. It was almost unusable because it covered up half the terminal window.
My old phone, a Palm Treo running PalmOS, was paid for by my previous company and so was the service. So, when I started a new job in May, I knew I needed to buy a new phone...
But, then over time, the phone got slow. And as T-Mobile pushed out new Android updates, the phone got slower and slower. It got to the point that when I would press the Home button, it would take up to a minute to display. The G1 supports using an SD card to store some data, music, pictures, and anything else to be accessed like a USB drive on your computer. But, the phone could not use it to store downloaded applications. As I added more apps and as Android added more features, my phone started to crawl. I got to the point that I couldn't stand it and wanted to throw it out the window.
Then, a co-worker (hi, Jonathan) told me about CyanogenMod. It's a hacked, customized version of the 1.6 version of the Android OS. In order to get it on the phone, you have to install an older version of android that had a flaw allowing one to gain administrative access to the phone. This then allows one to overwrite the recovery ROM which allows for installing a development version of the OS and Cyanogen's ROM.

Without CyanogenMod, my G1 was unusable. Now it is an extremely useful tool. It's a mobile web browser, mobile email client, SMS client, SSH client, Facebook client, music player, and much more. Oh, yeah, it's also a phone.
The Android platform is a great phone platform and it shows an incredible amount of potential. As an open source system, it allows people like Steve Kondik to make a so-so system into an amazing phone. An iPhone-killer maybe. :)
