LOL, Mac uses don't use them much anymore. Keep in mind, Macs are a SMALL share of the computer marketplace. SMALL!!!
lol.. really? with the popularities of netbooks/ultrabooks, more availability of high speed internet, im sorry to say DVDs are part of history.
Infact only 2 weeks back i bought my first ever mac(first time in my life) and ive been using windows based desktops/laptops since Windows 95/98 more than 16 years ago. So i can safely say usage of DVDs have nothing to do with Macs. Its just useless junk lest you are using legacy software that came on discs.
I still use my self assembled desktop which has a DVD writer and have been for nearly 4 years and to tell you the truth, baring the time i used to install Windows 7 from a dvd when i assembled the computer, ive used my dvd drive like 3 times ever. Last time i used it like a year back i found that the power cable was not even connected to the dvd drive(had removed it for some reason a year back).
Even the place i used to work(which employs like over 80k people, all pcs dont have dvd/cd drives. Only laptops have it cause it came with it from the vendor.
Please dont try to make it look like only people who use macs dont use Dvds.. cause even in the windows world its very very rarely used.
