OK --- I have been using this phone since day two of release. And I am having a lot of fun with it except for one thing -- using it in real time, day-to-day living. The Nexus is first and foremost a phone. But in that most fundamental way it is almost useless to me because of the battery drain. After playing with this thing, using and tinkering with every possible energy savings idea I can find --- I suspect you would not be able to go to work in the morning, make a dozen calls and surf the internet for 15 minutes and still have power for the commute home. If this is true then it begs the question ---- of what practical use is it?
