Sadly, OpenOffice is not ready for Prime-Time, mostly because everyone still uses the proprietary Office .doc format. Hopefully the move to open standards will fix the compatability issues, and OpenOffice will gain a better foothold. Nothing pisses me off more than opening a .doc in OpenOffice that doesn't render properly because someone used some feature in Office no one else even knows about.
That said, it doesn't matter what you're selling, you can't conspire to fix the price. Microsoft could sell donuts, it wouldn't matter, they still couldn't fix the price with a retail chain. Manufacturers put MSRP values on products, but the retail outlet gets to decide how much to charge (and in theory, that price is driven by what consumers are willing to pay, in theory).
