Several friends use garageband on their macs to record music/demos. I've never really used it other than to record an idea in a pinch. Today, at lunch I was sitting in my office and my acoustic was in there (normally it isn't) and my laptop was right there. Well, I burned a good 30-40 minutes playing around and ended up with this.
It's mostly just noodling around after the vocals drop out, but it was fun. I was shocked at how good the sound is considering I didn't use any mics, except for the built ins on my computer.
A far cry from using two tape decks to multitrack in my bedroom when I was 12. We live in amazing times.
