You look to be in the same boat that I was in. I am a n00b with tablets and received mine only a day or so after Diablo was released. Since you don't have any backups to restore from Chinook and you're getting a fresh N810 then you should be good to go. The first thing I did after opening the box was to download the updater to my PC and flash Diablo to it. The user experience out of the box was great since I really only played with Diablo. A fresh tablet updated straight to Diablo is quick and stable and I've not had a single browser crash on the device. Put your concerns aside and enjoy the tablet when it arrives.

Keep in mind that many that have been complaining of crashes appear to have restored a backup and something in that backup is causing an issue. Your fresh tablet will be fine.
