I just returned from the music store with a metronome for my son, who is playing the tuba. After I had shelled out about $50 for the item it occurred to me that I should have looked at the App Store first. You guessed it – there’s an app for that. And what’s more there were quite a lot to choose from for a minimal outlay.
I suppose it won’t be long before the app store becomes the default destination for anything specialised – the real item being the fallback. I’m sure it already is for a lot of people and it’s laggards like me that need to catch up!
