I would be prepared to pay. I wouldn't support anything that would take Linux out of the open source/GPL though. In a way, many of us have paid, even if none of the money went to the developers/distributors.
In some countries, bandwidth is expensive, both in terms of paying for the speed and download limits. With either extra charges for exceeding a preset limit or reducing available bandwisth to 28 kbit/s over a cable modem.
I started using Linux about 6 months ago while in the US (Phoenix). Through cable over there (no limits, US$45/month) I was able to download and play with several distributions. Mandrake was too easy. Fast install, and thereafter quite slow. Debian's install _didn't_ work. Had thought it would be easier than Gentoo.
Tried Gentoo. Fell in love.
I still dual boot with XP, but have now leant to hate it more than I did before. NT4 (post SP4) was the only decent OS that MS made, if any of their OS products could be classed as decent by comparison with what else is available. When I manage to get my scanner, printer and camera working, as well as Word in either wine or vmware, XP will be sent on a very short trip to /dev/null. It will happen.
In Linux, I can play any video or sound file or DVD that I have come across, rip CD's or DVD's to a choice of formats, and do any or all of those things smoothly _while_ recompiling all or part of my OS with different optimisations... Yes, I would pay for that.
Try even playing a DVD on a fresh XP install if you have lost the CD that came with the DVD player...
But then who among the dual booters out there has ever paid a cent to MS?
