I checked out the Nexus today. Gorgeous screen, didn't seem too big. But for me the dealbreaker is the radio. The signal strength was about 10 worse than my Inc and the Rezound/Razr. Since I already get bad signal in my office with the inc, I fear it would be non-existant with the Nexus.
the only time i've noticed the radio issue is when i'm in an area with a low signal strength to begin with... so that may be an issue if you say you already work in a low signal area, but they're supposed to address the signal issue on the next software update, which considering it's a nexus, should be pretty soon.
i also came from a 3G droid X to the Nexus, so i may not notice the radio issues with 4G as much as someone who's already had a 4G phone. we'll see how it goes when the next update rolls out.
as far as the screen being too big for the human hand... that's just silly. i have no issues reaching all corners of the phone when it sits in the palm of my hand.
the battery issue is TBD. you can't judge a phone's battery quality in the first week of use. A), you need to fully charge and drain a battery a few times to get the maximum usage from the battery... B) you're playing with the new phone so often, trying out all of it's features, etc. etc. during the first week that obviously you're going to drain the battery quicker than with normal usage.
also... google wallet is now fully flashable to the nexus, no root access needed. i've been buying stuff with it since sunday morning... the look on the face of the cashier alone is priceless.
add that in with a beautiful design, nexus access to software updates, and yea... the fucking software
... ice cream sandwich is amazing...
i love this phone.
