MORE ON the Google Nexus One phone. Also, Walt Mossberg likes it (subscriber only, alas): “In my tests, overall, the Nexus One worked very well. The latency I had seen in earlier Android phones is gone, due to a slicker version of the operating system and faster chips. The phone feels good in the hand and the screen is magnificent, with much greater resolution than the iPhone’s. . . . But there are some downsides to the Nexus One. Like all Android phones, it relies too much, in my view, on menus that create extra steps, including some menus that have a built-in ‘more’ button to display a secondary menu of choices.”
