Not just you guys, my N1 got BLAZINGLY FASTER since I manually updated it to Gingerbread. Oh god too much to name, so many speed increases from sending texts, loading the messaging app, starting up apps, UI interactions in general have gotten way faster, smoother and zippier, and the GPS is also even better, faster and accurate. And not to mention all the good looks of Gingerbread.
I love it, makes me wanna buy a Nexus S asap which I have to do cause of the touchscreen calibration issues on my N1, it wrongly senses where I touch it at sometimes so sometimes the wrong letter gets hit on the keyboard, it happens a little but it's still so annoying. It definitely declined a bit on Gingerbread, probably because of the way better keyboard. Still a bit annoying though, and then you have the other touchscreen calibration issues aside from the keyboard like when you choose a thread in messaging, sometimes it selects the wrong one when you touch it and if you're not paying attention or trying to text quick you might send the text to the wrong person, happened to me a bunch of times but I pay more attention now. It's still under warranty till March something but idk if they might say it's a bit of my fault, I dropped it slightly once and the right side of the back cover has a gap between where it's supposed to hit with and connect to the phone on the side, maybe that side of the touchscreen got hit in a little or something which causes the calibration issues. I guess I could try it since it might not be my fault but I don't wanna be without my phone. I think HTC actually sends u a refurbished replacement N1 first actually and keeps your credit card on hold till they get the old one back, but I don't want them charging me after for the old one and saying it was my fault, that'd suck.
