I've spent a couple of hours looking at a digital system for learning to play music. I watched all the free videos and thought about whether I would follow along with this system:

I've already downloaded one of their programs called Finale NotePad to writing music down. It is free and does a really good job of what it does. I can't imagine I'll ever need the features the for-money versions provides. I downloaded the SmartMusic system demo, but i haven't double-clicked the DMG file to install it on my computer yet. The documentation and videos continuously state that the system is designed to be used with a live teacher, and I can't afford that. Still, indulging my curiosity by looking at their free stuff has been interesting.
The upgrade Apple provided that allowed my cute little Bluetooth keyboard to operate correctly without a hitch has really pleased me. If it had worked this well right away I wouldn't have purchased the USB wired version, but it didn't work so well when i first bought into the Bluetooth hype, and I did buy the full-sized keyboard. I just switched back to the wired keyboard because of the additional features that make it easier to use for writing. I especially like having that second Delete key that deletes stuff to the right side of the cursor.
I had to buy a new mouse. The old one just reached it's ring-pass-me-not when the scroll wheel just stopped working. I have another USB wired mouse that doesn't move on the surface of my desk but has a big ball to move the cursor around. I got it out and hooked it up long enough to find out if the scroll wheel worked on it. It did just fine, but the other attributes of that type of mouse still irritated me, so I went to Radio Shack and bought a new one and paid way too much. Amazingly, the wired USB version costs more than the wireless ones. I don't like the wireless mice. They don't always work and the wired one always do. What's to figure?
