Habitually applying firmware updates WILL bite you eventually, especially those that are hot off the grill.
Very true. At first I just skimmed the title and thought their fix to the 1.5 TB drive problem bricked them. At least then those people had a definite reason to apply the firmware. Trying to have the latest will bite you in the butt.
Even then I wouldn't do it though. I always give some time and then cruise the forums for any problems before I do any firmware or major software update. I let them risk the pain at the cost to me of maybe a few days of lesser functionality or security, or maybe a month in the case of a full OS X upgrade. I believe that is a good trade-off.
I'd take it even further. Habitually applying ANY updates WILL bite you eventually, especially those that are hot off the grill.
Iffen it ain't broke don't fix it.
Has worked for me for many years.
