Quote from almostatrader:
I've heard of traders running three, four or more computers all at once for trading. They have each computer loaded with Windows XP and Microsoft Office. If they actually bought separate legal licences for each computer it could be very expensive. Most traders are smart enough to find ways of having to avoid buying separate licences for each computer. However Microsoft has a lot of smarter people working for them and eventually they'll make it impossible to bypass the licencing requirements. What will the traders do at that point? Will they have to pay up or could they possibly start running Linux on all of their machines?
