It would seem Windows is the least commercially viable platform for anything media related. I think if Pioneer DJ were serious about the user experience Linux would be a serious consideration, especially after the XP source code was leaked meaning hackers now know the system architecture almost inside out. Think for the future and the possibility of Windows being GONE because it's too unsafe to use, do you think everyone will just switch to Macs in that senario? Also Linux uses by far fewer system resourses meaning there are fewer chances of system hiccups and doesn't waste CPU and memory for garbage.
You've had people offer to do it for free and yet you still won't so I have to ask, is it only so Pioneer DJ can play 'God' with the equiptment sold?
