That last result may reflect a rare bug in the Nexus's software, to judge from reports on Reddit. Plus, my brother bought one and hasn't had this issue.
The $199.99 Nitro HD won an unfair edge in Vegas: a glitch kept it off AT&T's new LTE service, prolonging its battery life. But having to try online tasks again and again on a maxed-out 3G network often negated that advantage, requiring a recharge by early afternoon.
Back in the Washington area with LTE engaged, the Nitro allowed 4 1/2 hours of Web radio with its 4.5-in. screen lit, then had 64 percent of a charge left after 24 hours idling. That's still bad.
On both phones, LTE drove shockingly fast downloads - usually at least 10 million bits per second, maxing out at 26.6 Mbps on AT&T. But it's often hard to discern that extra speed on the screen.
Software set these phones apart more than anything else.
The Nexus is the first U.S. phone to ship with Android 4.0, Ice Cream Sandwich. That change may confuse Android veterans: ICS replaces the traditional back, home, menu and search buttons with a new lineup of back, home and recent shortcuts at the bottom of the screen.
