Not directing this at anyone in particular but I think the Axe is a lot of users first high end digital audio device. If your a "dumb" guitarist (I say that lovingly) updating OS etc is kind of a a foreign concept compared to analog hardware gear.
I see the same thing on photo forums, where a lot of users don't know how to update a camera firmware, are afraid to do so etc. Other users can't wait for each new firmware as it adds new features, improved focus etc.
I think most Axe users who have had the units a while know about updates and can't wait for them. If you just bought your unit though, have no clue about all the cool stuff it adds, its just this kind of scary concept you've never done before and that makes you worry about doing something to break your new $2300 toy.
Understandable I think, at least until you do it, and realize how quick and easy it is, then you join the masses that check the site 3 times a day hoping for news of a new FW update lol
