True, flash is not Open Source, but I do not have to pay for it.  My video drivers are not open source either. I don't think I will be giving up my drivers anytime soon.  I do not use the wine, Firefox, flash combo personally, however I did have to set that up for my kids, as some of their favorite sites require the newer versions of flash.  Personally I don't frequent Barney or Barbie, so I have no use for it myself.

For me, the Freedom part of "Free" software is having the ability to choose what I want to run on my computer.  Would I buy a video game if it were available for Linux at my local retail outlet?  You bet I would!  Would I pay for drivers to get my printer or graphics card to work?  Heck no! Those drivers should be available for my "choice" of operating system, not someone elses idea of what I should be running.  There are quite a few software titles I would be willing to purchase if they were available for Linux.  Luckily I have been able to find open source alternatives for most things that are readily available to download for free.

MS free since 1999, sorry uncle Billy!
