[Nexus One General] formatamerica:
Background Info - I'm coming from a G1, before that WinMo (HTC Herald lol). Outside of playing with an iPhone for a few times I have zero experience with the Apple lineup. Pre? Who cares.

I've had my N1 for about a week now, so I've had some time to run through the gamut of features and I'm already quite familiar with Android so I have a good basis of comparison.

General - This phone feels really nice and solid in the hand. It's smaller and thinner than an iphone and WAY smaller than the G1, but it still has a nice heft to it (although it dodges the Droid's brick-like feel).

Screen

The glass screen is scratch resistant and the touch response is nothing short of awesome. Some people reported issues with the soft buttons at the bottom of the screen, I can't think of any times where I've been frustrated with them failing to register taps.

The color and brightness took a little getting used to- it was different than the G1 and I automatically associated that with "bad." However, after comparing the two in various places, I realized my opinion was more due to familiarity than any objective measure. The N1's screen is crisp and bright, the color representation is very good and I quickly lost my attachment to the G1's washed-out display.

Speed - Holy crap. The speed difference between this and the G1 is like night and day. There is quite literally no comparison to anything that the G1 does. The N1 boots in no time at all, all phone functions are extremely responsive and there's only an occasional hiccup in scrolling or animation (nothing that effects the user experience at all). Complaining about a slight animation stutter when your homescreen still snaps up instantly isn't really reasonable, IMO.

Keyboard - Improved IME over the G1, adds a few nice touches like swipe actions. Due to the larger screen size, typing is considerably easier and, although I'm a huge hardware keyboard fan, I don't find myself struggling or getting irritated with the soft keyboard at all. It's responsive, my only wish is that multi-touch was enabled.

Applications - Many of the "Must Have" applications that I purchased for my G1 are no longer useful on the N1 because of the additional functionality with the OS updates. The market works and works well for what I need. There's an "app for that" in almost every case, the only glaring exception is the lack of a non-****ty music player. The Android default gets the job done, but it's not pretty and every other available application tacks on some useless feature- I just want to play music goddammit.

Email/Calendar - The GMail application is great, the calendar works but Exchange compatibility could use some improvement. Currently, there's no super simple way to get your exchange calendar working (I'm pushing my work calendar to my phone via google calendar sync) and HTML exchange e-mail is not supported. Lame, but it's not the end of the world. 3rd party applications address this, Touchdown seems to be the most actively developed exchange application, its interface is a little ugly but HTML e-mail support is solid (also it'll run you like $25.00).

Camera - Considerable improvement over the G1, it focuses and captures pictures faster and the quality is pretty superb for a phone. The flash is good for illuminating nearby objects, but it's useless past four or five feet.

Music - 3.5mm jack is great to have, I use it to listen to music and Pandora in my car and while I'm out and about. Music quality is pretty good, but it distorts on max volume. One change that I LOVE coming from 1.6 is that notification sounds seem to play over the phone's default speaker at all times. This prevents a ****ING DEAFENING alert from playing while listening to music.

Battery - A day at work: 12 hours, 200 exchange e-mails, 15 personal e-mails, a few hundred tweets, a couple hours of Pandora, 20 text messages, a few calls and a bunch of miscellaneous use will leave me around 15% battery when I get home.

Phone - The least used feature for me :) The loudspeaker is OK, but the proximity sensor and second mic work wonders to improve the calling experience. It feels good to use this phone for calls, it's kind of hard to elaborate on that.

Conclusion - It's pretty great, I think it delivers an awesome Android experience and, with a bugfix update or two, I will be 100% satisfied. Native exchange support leaves a lot to be desired, but like I said before 3rd party applications fill the gap adequately (you can't have everything, right?). I can't fully underscore how fast and responsive this phone is and from what I understand it's only going to get better with the addition of 100-150MB of ram in an upcoming patch.
