I see your point, but then you have to carry around an extra charging device (battery powered charger if I understand you correctly). I would prefer a much improved battery life with the current battery (which is possible once a proper sleep mode is implemented through updated ROMs). Right now the idle process eats as much battery as a full blown app running, so we need to figure all that out (along with possible CPU throttling). Then we will see what additional chargers are needed.PS. My primary reason for purchase was for my daughter to use it in the car during long trips (the in laws live 3+ hours away). This way she can watch some cartoons, play some simple touch screen games, read some books, etc. Also, I can turn on MyFi on my iphone (wifi tethering app) and let the wife check some things online. I already have an inverter, so no additional charging accessory is necessary. My secondary reason for purchase was because I love the android OS and love to tinker with devices as well, this let's me do both. ;D
