While offering classical movies may be of interest to some, there are very, very few movies I care to watch more than once. My preference is more varied content that changes, so there is something new each time I travel.

As for storing multi-TBytes of content, there are costs. The storage cost is just one but there is the licensing fees also to considering. Additionally there is the issue of how to present and allow the user to select 100's of selections. Especially if you assume for an expanded movie selection you would have an expanded TV selections and music selections.

Of course a paid system, might be more extensive but I prefer the system stays free.
