Just because its not as easily swappable doesn't mean it can't be replaced. I'm actually curious how difficult it is to swap. If the back still comes off (which we know it does), then it really comes down to how hard they make it to remove. Just guessing here, but ites probably the same as the Gnex except it has the ribbon connected to the battery instead of pins. Can someone disprove this?
And to keep thread on topic...my 32gb black nexus arrives Wednesday.
Not sure how LG built this. HTC once mentioned that they put battery sandwiched between screen and circuit-board to minimize the phone profile and balance the weight. Goog luck swap battery on that one.
