[G1 General] pjcforpres:
I just finished my 24 hour testing of the Nexus One for my employer and figured I would give my 2 cents worth:

1. On screen keyboard: Great, especially when used in landscape. Portrait has a bit more room side to side than the G1, and it makes it easier, but I wouldn't go so far to say in protrait it is a night and day difference. Landscape truly is, and I had no problem typing long messages in landscape mode, and using portrait for quick stuff. A physical keyboard is still a better option, IMO as a keyboard lover, but the onscreen is executed very, very well.

2. Speed/Android 2.1: I have tested some of the 2.1 ports on my G1, and as nice as they are, they do not give justice at all too what 2.1 is on a Nexus One. Blanket statement, the phone is faster and 2.1 is a great advancement. A more astute observation that I wasn't expecting, websites load much, much, much faster on the Nexus One. I didn't do an actual stop watch test, but a realistic guess says sites load about twice as fast. I am on an EDGE network where I do most of my surfing when not using WiFi... when on WiFi it was more dramatic (I actually loaded 1 site faster on the Nexus One than on my computer)

3. Stability: I tried my absolute best to slow it down and make it unstable. Couldn't do it. At one point in time, I had 23 apps open, the browser had 3 windows, I had youtube running, music, and so forth. Of course, several of the apps had to "reload" the last point I was at, but with this phone "reloading" is pretty much instant. The longest it ever took was one of the web pages had to re-download the content. I found that the phone's cache held my normal use just fine without ever having to reload.

4. Fit/Finish/Style: The phone has a very solid feel too, despite being very light in weight. Fits well in the hand, comfortable being used as a phone, and I got a lot of comments on it when I was out and about testing the "wow" factor (I was asked to go to a busy restaurant/bar and see how many people asked me about it). And, as odd as this might sound, being right handed the back button being on the far left was not a big deal, and I actually liked it's placement a lot since when I used it in landscape mode it was much more comfortable hitting it, and I think this is what they had in mind when they designed in like that.

5. Battery Life: Damn! That is all you need to know, Damn! I tried, really, really hard to push this to the max and see how fast I could run it down. I had WiFi and GPS both going, music playing, and was surfing the web as quick as possible, messing around with google maps taking a look at new and interesting places, and gave up. I used 80% of the battery in those 24 hours, but I was trying my best, for a little above typical usage it only went down 20% from 9AM-5PM. My G1 is usually about 60% gone over that period.

6. Conclusion: I am someone that pretty much demands a physical keyboard for me to even think about buying a phone. I am getting a Nexus One as soon as they become available through the company I work for. My manager is a BB addict, and she said as soon as we get it she is switching as well. That is a huge statement, her daily phone is a BB 9700, she texts and writes most of her emails from her phone, and the Nexus One out performed her BB 9700. She was using the google voice service to write, but she said out of all the texts and emails she wrote using it she didn't have a single typo!
