Now that I’ve had a few weeks to play around with my Nexus One, here are a few observations I’ve made:

• I can’t live without the CyanogenMod ROM. Android 2.1 is nice, but the tweaks available in CM 5.x are too numerous to mention and offer many features that go well beyond what the N1 can do out-of-box. If you have an N1 (the TMO version, or the Rogers/AT&T one), get CyanogenMod. You’ll never go back.
• The screen is, by far, the best I’ve seen on smart phone – it trumps my old iPhone 3G at every turn. Some people argue that the screen has a purple hue to it, but to them I ask, have you heard of Colour Temperature?
• The last three phones I’ve had (an iPhone 3G, an HTC Dream, and an HTC Magic) have all had noticeable lag on the main screens and when load applications. The N1, both with the stock ROM (that I had left on for all of around an hour) and CyanogenMod simply scream. There’s nothing slow about this phone.
• For all of those who say that the signal quality on the N1 is crap, please actually get one before forming an opinion. I’ve seen an increase in signal strength/quality on the N1 over the other HTC phones I’ve had, and over the iPhone 3G. Additionally, I’ve been able able to clock download speeds greater than 3Mbit/s on Rogers’ HSDPA network. Not too bad at all.
• The camera is amazing – the fast auto-focus, bright flash, and fine-grain controls are simply amazing, and at 5 mega pixels, the picture quality is simply staggering for a smart phone.
• My only real complaint about the N1 is battery life, but then again, I’m always complaining about that (the exception being my MSI Wind U123 with it’s 9 cell battery that gives me 8 hours of use). Under heavy usage, I have to charge the phone nightly. For that reason, I bought an extra battery with the phone, however as I have a power inverter for the car that features a USB port, I didn’t really need to get the spare.

That’s really about it for now. Overall, the N1 is an excellent phone, and I wouldn’t hesitate to recommend it anyone.
