I had lots of apprehension about installing Diablo because I'm not exactly bursting with knowledge had things gone pear shape, but I was actually surprised at how smooth it all went. This is also coming from someone that restored their full backup from chinook and found no issues with Diablo. Have I been one of the lucky ones; I don't know. What I do know is I had a lot of anxiety before the update, but now I'm just kind of relieved and hope I never have to do a firmware flash again now that Diablo has an all new way of providing us with upgrades.
