My challenge to Apple/Emagic, as a former Emagic user and corporate supporter, is to substantiate their numbers and show step-by-step how you got to your results and conclusions, with what optimizations, and with what equipment, so it can be replicated by you, the Apple customer.
That's fair and reasonable.
Second, I don't need Apple products. I have a PC setup for sequencing, GigaStudio, and separate VSTi computer that works,syncs to SMPTE, and does everything professionally needed of me as a professional composer in Los Angeles. So on that basis, I have no need to switch. Also, as a PC user, I have MIDIoverLAN and therefore save hundreds of dollars in avoiding hardware MIDI interfaces. When FX Teleport is completed to the point that it supports GigaStudio (hopefully starting with 2.5), I'll be able to save thousands of dollars in system expansion because I won't need audio cards in my other computers, only the sequencing master.
Third, if I did switch to the Mac, it would not be because it's the "thing to do." I would switch, or add to my current system for one of two reasons:
1. I found myself in a situation where my colleagues were using Digital Performer I needed it for continued work;
2. The new G5 proved that Mac-based software synths and samplers run more effectively and efficiently with both more RAM and polyphony than their PC counterparts.
Otherwise, I have a working system, the world's greatest orchestral library, and no hype. And that's a fact!
