Big mistake. I need my DVD drive to watch movies, and Netflix doesn’t deliver them on SD card.
A lot of people watched movies on Beta Tapes... then on VHS Tapes... then on Laser Disks... now DVDs... Netflix does provide downloadable movies. It's only a small step to sending out movies on SD cards instead.
Netflix does do streaming video. ..and you can rip DVDs to SD cards.
That said, DVD disks are a great cheap distribution medium. Pressed disks are cheap and quick to produce. They (and Blu Ray) will remain a staple of the retail store for at least 10 years.
DVD drives will quickly disappear from laptops. They make the computers larger and more fragile than necessary. Remove the DVD and spinning hard drive and you can build a tiny, robust computing device.
IMHO, the next generation of small laptops will be tablets. For portable operation, you can use a soft keyboard like an iPHone. Heavier users can use a bluetooth or usb keyboard. With a tablet design, you also get rid of the hinge, which is the other weak link of the laptop design.
For the sake of argument, I’m typing this post on an Apple bluetooth keyboard that is small enough to fit into a laptop case.
I envision the day where the mailings will stop and Netflix can only be downloaded.
