Not trolling, really. I'm curious why folks updated so quickly.
With software updates in general, and SD firmware updates specifically, I wait a couple months to update unless there's a compelling bug fix or new feature.
I don't run a mp-10, so maybe I'm missing something important there, but for the MP-6, only significant change was the addition of pre-roll. That doesn't seem compelling to me on a deck which is easily powered for a long time and can use huge SD cards.
These days I start recording 15 minutes before the set, and leave it going through intermission if there is one. Easy to trim in post, and no chance of losing part of a set.
So, why update immediately?
