I bought a copy of Up yesterday. For just a couple bucks more than the Blu-ray version, I got the four disc set which came with a regular DVD of the movie so the kids can watch it in the car or take it to the Grandparent’s, neither of which have a Blu-ray player. It also came with a fourth disc that opens up iTunes when inserted into a Mac/PC. You enter in a code that’s included in the packaging and a portable-sized version gets copied off the disc, ready to be installed on your iPod/iPhone. I think you can also get versions that will play on non-iWhatever devices.
For four bucks, it’s definitely worth saving the trouble of ripping/converting/burning. Why did it take so long for a studio to think of this?
