For music creation they recommend using a separate HD, and I also want to set up mirror RAIDs for data backup, so those four drive bays in a Mac Pro are looking mighty enticing. I've finally decided to start saving up funds for the rumored six-core Mac Pro update this summer. Don't quite have the means to drop $3K on a MP and $2K on a MBP. One or the other.
If you need a physically separate,high-speed internal drive for music recording, ignore this. Otherwise, it sounds like you might be well served by an iMac with external harddrives and/or Drobo (or other RAID / NAS. Backup doesn't need to be fast, just reliable). And that top-end 27" iMac (i7) is cheaper than a "modest" Mac Pro without a monitor.
Add an iPad to complement your professional kit for casual, personal use.
