After using the Nexus One for a week, I've concluded that I would have gotten the Blackberry Bold 2 over this.
A bit of background: I use the BB Bold 1 for work & also used the Nokia E71 prior to the Nexus 1.
Pros:
Beautiful Screen - Not just the colors, the its true blacks are pretty darn awesome.
Camera - The camera + flash seems to be doing pretty damn well in low light (for a camera phone).
Build - seems pretty sturdy right now, thinner than Iphone.
Cool factor - "its the google phone" gets the girls in your hot shorts.
Cons:
Battery Life - Totally sucks ass. I have a charger at home, at work, and at my girlfriends home. I use the phone primarily for msging on gtalk/emailing/phonecalls w/ GPS/Bluetooth/Wifi disabled. I don't get how it will be a "superphone" which can leverage the connectivity & apps if it lasts half a day w/ a few crapshit apps on.
Touchscreen - I make calls, send loads of texts/IM. Coming from a BB background, physical keyboards make my life much easier and more efficient. Takes me 1 minute to type a message that I can accomplish in 20 seconds on the BB. Disclaimer: My friends tell me its because I'm a touchscreen Noob. Iphone users tell me the N1 keyboard is the same as the Iphones.
Apps -
Where the fark are my apps!
Can't use google voice because I'm in Asia,
Gaming is crap, the VoIP apps which I got it for doesn't have a good option right now (Skype lite charges vs the free iphone version), and the
Facebook app sucks dick. E.g. I can view my own photos on its native app, which gives me fullscreen viewing - but when I click on my friends photos, it opens the browser and directs me to m.facebook.com. Great.
Music default app sucks cock. Can't do a lot of navigating properly and how the hell do I import Album art properly...and syncing?? where SYNCING!!!!!! Also, my friend tells me: "dude, your N1 can't even produce enough bass to power my headphones properly". I tried looking for an equalizer to blast his eardrums and prove that my N1 was the shizzles. None.
Localized & HK Personalized apps from HTC which was awesome for many Hong Kong HTC android users - e.g. Bus/Train/Public transport route app, HK's best restaurant review app, all blocked by N1. (Error: can only be used by HTC phones)
