The T-Mobile G1 is a mixed bag. It's not as polished as other smartphones, but thanks to Android it's got a bit of "wild west" feel to it that will appeal to early adopters. With this comes a bit of inconsistency with the Android GUI, a paltry selection of apps in the Android Market and at times the G1 feeling a bit incomplete. Taking all of this into consideration, the T-Mobile G1 is a blast to use. Android being an open OS will only get better with time. The interface is fast, fun, easy to use and the expectation of third party developers "filling the gaps" more than makes up for the current faults of the OS. The hardware lacks the wow factor when it comes to design and it can be difficult to type on the QWERTY keyboard. All things considered, the T-Mobile G1 seems like a value at $179 when you consider it includes GPS, WiFi, 3.2 megapixel camera and an ever expanding offering of applications in the Android Market. If you are considering the G1, just remember it's all about the destination, but expect a bumpy road.

Pros:

Offers a host of features including GPS, WiFi, touch screen, 3.2 megapixel camera
Priced below other smartphones and a value for what's included
Android Market offers great selection of free apps
Web browser on par with mobile Safari offering up the "real Internet" on a mobile device
Open source OS will lead to more software choices for consumer
Trackball is simply fantastic and very useful when navigating the UI or the web
It's fun or should I say funnerer
Google Maps not as accurate as iPhone version

Cons:

Battery life
Hardware lacks "wow" factor
Lack of desktop app makes it difficult to sync your with traditional apps (iTunes, Outlook)
Unable to open Office or PDF documents

Overall, very good... better battery life would make it GREAT.
