i'm still on my first one, been running strong since early december. assembled in mexico, for what that's worth; i know where it comes from has some impact on hardware life/performance. Aside from a little dust under the screen (only within the past month or two), it's been great, even through all the bumps and drops i've put it through (dropped it off the back of a pickup truck, etc.).
i knew what i was getting into, buying a first gen device, and while annoying/frustrating at times, i can still say i've enjoyed the ride, being addicted to checking for updates and hybrids. that being said, i still can't wait for storm 2.
