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.
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.
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.
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)
