I ordered a Nexus One the day it was available. It has now been about 6 months since I first got the phone. Since then, I upgraded to Froyo (Android 2.2) when it was available. (Update: I now run Cyanogenmod RC3)
Here is a review of how things are progressing with my phone, with the Froyo update.
First and foremost:
It is pretty good, except when I am trying to hold my phone in a shoulder hold.
I do have issues with some phone calls dropping, but I think it that is T-Mobile’s fault
I have to charge it everyday. I doubt there are other smart phones that can sustain being under heavy use and last for more than a day.
Under excessive use, like using the phone browser for 4-5 hours, while listening to music (you get the idea), the battery life is even shorter. For this reason, I now have a USB cable on my desk at work, and a car dock that charges it in the car (See more below).
Cyanogenmod Update: Battery life is so much better with this update.
Being able to look up information at a quick glance is one of the reasons I got this phone. The stock browser just absolutely kicks ass. Given the fact I have the Adobe Flash plugin (works ok, not for extensive use!) on this phone, I can pretty much access more information available on the internet.
I would like to see the stock browser supporting tabs (or switching windows using some kind of gesture). I know dolphin and xscope browsers support this, but I would like the stock app to get this feature someday.
Cyanogenmod Update: Has incognito mode. Yay!
Google maps with turn by turn navigation is pretty sweet. I have now taken it on two trips (i did carry my gps in my bag incase my phone failed me), and it was pretty easy to use.
I did not like the default mail client that came with android. I replaced it with k-9 mail for my work email. I use the gmail client for my gmail.
I do not like the default calendar. The blackberry calendar is much more solid. I do like the sync between google calendar and it showing up on my phone automatically. I have tried Gemini calendar for a while, and have now settled on Jorte. Jorte provides what I need to know at a glance, with the weekly view.
Edit contacts within Gmail, and it gets added to your phone. Or the other way around. Two way sync is very nice
Market works like google search with suggestions. Very easy to find what you need. Get appbrain if you find this inadequate.
The stock music player is pretty basic. Sorted by Album/Artist/Song/Playlist.
I like folders, and use mortplayer.
Cyanogenmod Update: Musicmod is very nice, but I still prefer mortplayer
Listen is ok with the google reader implementation. Searching for podcasts in listen is confusing. I prefer to search and add subscriptions within Google Reader. Also, if your podcast is not downloaded completely, it has issues playing the podcast. I always finish download of the entire podcast before I start playing.
The camera is pretty good. The flash works well (and doubles as a flash light!).
The pictures are good enough, and at night – even better than my Canon S3IS!
Cyanogenmod: Adds 720p video shooting.
