Cubase VST was doing 32 track audio flawlessly on Windows back in the late 90s on an original Pentium. Seriously weird seeing people demanding more power for audio work.
That's like saying people were multitasking just fine on Windows 3.11, so why would anyone want a modern OS? If you want to work at a professional level and produce music that actually sounds good you need to work with high resolution audio files and complex, CPU-intensive plugins.
Unless, of course, you own extremely expensive hardware or happen to be a lo-fi genius like Bob Pollard or Calvin Johnson :)
