Hello, I would like to start producing digital art be it music, movies, etc. I want to start with music. I found a local craigslist ad that posts a macbook pro with all the software to get me started. Here's the link: http://grandrapids.craigslist.org/sys/2532584360.html I'm wondering if this is a good deal and a good way to start as a beginner? Are these a good set of programs? Is this a better choice than an iMac or iPad?
