Additionally, some Nexus 7 owners, root their devices, which includes unlocking the bootloader, installing a super user app, and adding additional android commands and optionally installing a custom recovery. At this point, many users, like myself, enjoy the benefits of root, without replacing the stock OS, with a custom ROM. Admittedly, in the event that I find a custom ROM that offers benefits that interest me, I will consider using that ROM, but currently I remain happy with the stock OS. I agree that there is always the possibility of bricking your Nexus 7, but consider it very unlikely with the one click toolkits and recovery options currently available. I suggest, that if you have interest in learning about the benefits and pitfalls of rooting, that you read our forum's guide to rooting.
