Good phone. I came from Blackberry -> HTC Desire -> iPhone 4. Of which the iPhone for was the best by a longshot.
I kinda disliked Android, not consistent, lot's of crashing (like 100% of the time when I tried to turn of the phone).
The Nexus 7 turned me around on that, which gave me the confidence to buy this phone.
Battery is ok, I'm at 60% after 2,5 hours of intensive use. Better than my iPhone 4, but not impressive.
Build quality seems good, feels good in my hand, backside has nice grip.
Screen is very nice, watching Netflix is beautiful on this thing.
Android runs well now, nu strange hiccups or crashes. All my favorite (ios) apps are there as well.
Overall speed is a delight, I'm no longer waiting 20 seconds for Chrome to start up.
Google now integration is great, much more useful than on a tablet that doesn't leave my house.
Phone call quality is good.
Camera has been disappointing thus far, might be because I only used it in low light settings.
I'm deep into the Picasa, Gmail ecosystem, so that's all great to have it this neatly integrated.
One of these impressions is about my gf.
