The reason for no 3g/4g is because of brain cancer risks. They dont want the radio to sit that close to your brain. Based on the conversation, bluetooth teather looks like it will be the way things are done for a while. On the other hand, Android 4.3 should include Bluetooth 4 LE, and I believe Glass will also be capable – that should save juice!Chaim Cohen – 2013-07-01 00:15:44-0400I think the tethering is fine. In fact tethering may use less battery because you are not constantly turning on the display.Scott GrantSmith – 2013-07-01 00:18:19-0400Like +Mike Elgan wrote yesterday, I think we’re heading for carrying a cluster of interconnected devices and the phone (or phablet, in Mike’s estimation) will be the outward-bound connection and the rest will be connected to it by Bluetooth. I wish the handset manufacturers would give up on the race-to-paper-thin-phones and make one with a decent battery.Gary G – 2013-07-01 00:21:05-0400+Wayne May your insight explains the method to the madness. They are very smart to keep the radio out due to possible brain cancer.Wayne May – 2013-07-01 00:25:21-0400+Gary Gonzalez they have a lot on the line, I am sure they dont want to deal with negative health PR issues. I wear Glass all day, every day, so the less risk the better 🙂Thomas Schwartz – 2013-07-01 01:18:01-0400I would have to disagree. I think that battery life needs to be improved on current smartphones. Motorola has already stated that battery life is one of their top priorities, so we will have to seeBenjamin Higginbotham – 2013-07-01 01:50:24-0400As it is now the battery presses against my head throughout the day. After 8 hours it really starts to hurt. If anything I want a smaller battery on glass, or at least something that keeps the weight off my ear. 4g would be nice, but I think comfort is more important right now.
