On second thought, I guess that after so many years doing this, I sometimes tend to forget that we develop a certain "expertise". Though I should know better because I'm quite often asked to give crash courses. I guess that knowledge may be worth something after all... :s
Just a few weeks ago, we had dinner w/ a couple of friends and the guy asked me if I could help him w/ his little Roland 4 tracks digital recorder which he'd bought to record his wife's demo. Sure, I said...
But having noticed that they had a couple of MacBooks in the house and an iPad, my first thought was - man, I wish you'd asked me
before you bought that 4 tracks.
And of course as we started talking about what the thing could and couldn't do, it wasn't long before I mentioned GarageBand - the concepts of which, I realized once again, aren't as obvious to every one as I tend to assume they are.
