An Android Community user - and T-Mobile Store Manager in Florida, apparently - who goes by kaziko has posted the first user review of T-Mobile's G1 Android phone.  The review - which takes the form of an ongoing forum thread - is summarized nicely in this post if you don't care to dive into the 11+ page thread. Of course, if you do there's text galore to tide you over until those G1s start shipping on the 22nd.

So what's kaziko think of the G1 so far?  A few highlights from his review:

• The G1 is like a "Sidekick on steroids" 
• It doesn't "run as smoothly as you would think" and some apps "stutter" as they boot
• On the other hand, the device boots (powers up) much faster than other HTC phones
  
• Kaziko encountered what he deemed a massive memory leak that forced him to reboot.  And often.
• The hardware is nice, with a pleasantly light weight and sturdy-feeling keyboard
• Video playback is limited and there's no file manager onboard ... though there seems to be some debate about this in the forums
• The Android Market is sweet: Easy to use, relatively full of useful stuff already

Okay, enough cut and paste.  Go read the review if you're interested.  I'll tell you what I think of the G1 just as soon as I can ...
