Today on twitter someone forwarded a link for a movie trailer. The link led me to an iTunes movie trailer service. In order to play it there was some software that I needed to download. However, it seems that the software was only available for Mac and PC. I could not find a page that would produce a download link on my Google Chromebook, which probably runs on some sort of Android operating system platform.
Unfortunately, itunes does not provide a version for Linux nor, presumably, any Unix-based OS. So it's not just a problem with certain notebook computers. I tried to install the Windows version of itunes with Wine. It appeared to install, but complained that an essential component was missing. It appeared the missing component was used only for copying files from a CD, and I'm quite sure it wouldn't install correctly because of DRM issues. Of course itunes could work without it and be useful for many things, and any non-DRM-protected CD could easily have their files copied by other software. But no, they will not allow use of any of their functionality unless it is entirely contained within their safe little box.
