The guys at iFixit are at it again and just posted their Nexus 7 teardown guide. Overall, iFixit found that the device is rather serviceable and seemingly well designed. Unlike the iPad 2 and new iPad, the Nexus 7 employs clips to hold the whole assembly together. This results in an extra 1mm of thickness, but they allow owners to open the case with just a little prying. Once inside, the battery can be replaced with ease; it doesn't even require the removal of any screws.
