Okay, so I'm actually Swyping this from my AT&T N1 right now. I'll have to echo most of what everyone's said so far. Yes, the dual-touch screen is wonky often. And yes, the power switch is prone to failure (thankfully, mine hasn't completely died, but I suspect some nasty debouncing problems). The pathetically miniscule (by today's standards) internal memory used to be a problem for me, but that was before I discovered A2SD/IA2SD/S2E. You pair a nice 32GB Class 4+ microSD card with the N1 and there is virtually no limit to the amount of apps you can install simultaneously. The official Android A2SD blows as it doesn't move the Dalvik cache, which is nearly the same size as the APKs themselves! Oh, and if you do end up getting one, DO NOT UNDER ANY CIRCUMSTANCES, use "deathray mode" on the Torch app! It'll end up burning off the phosphor on the flash LED and turning your nice white light into a deep blue. Trust me on this one =P I'm getting a replacement from eBay soonish for that. Let's see, what else... The GSM antenna placement on the bottom of the device is unfortunate, especially if you're using it in a place with marginal signal strength. However, that tends to be par for the course for mobile design these days, so I wouldn't hold that too much against them. Plus, if you REALLY need to, you can just install a custom ROM (i.e. CM7) that allows for 180° screen rotation and hold the phone upside-down for better reception. LOL! Hmm, almost out of experiences to share. I guess if you're rather rough to your device and don't use a protector on it, the soft rubberized coating on the case will eventually wear off and leave the device looking like a blotchy mess. I happen to think it adds character, but I'm funny like that

The screen glass is a BEAST! Not one scratch on it, even when it's been in my pocket with car keys and sand from the shores of California. Screen protectors be damned! The trackball is a nice touch. It makes editing text so much easier than even some of the newer phones I've played with at the AT&T and Verizon stores. Speakerphone quality is decent. Earpiece...not so much, IMO. That's why I insist on a quality Bluetooth earpiece for everything. It's purely practical, not cuz I'm trying to be a "douche". Lastly, and probably most importantly, it's got a fine legacy of developer support. It's refreshing that after nearly 2 years of me owning this phone, I am never bored. Then again, my phone before that was an ancient Windows Mobile device, so I guess my expectations might have been a little low at the time

Anyway, it has been, overall, the best investment I've made in my entire life in tech. It's sad that neither HTC nor Google are supporting new drivers anymore, but I can't really blame them. It's been a good, long ride.
