What's the difference between that and any other type of media on the internet? Take YouTube videos for example. An MP4 video file is also "nothing but a regular file served from a web page," yet YouTube doesn't include a "download" link for any videos on their site.
Right. So one has to install additional software to automate jumping through their hoops and download the MP4 file. In other words: no difference – I wish they would just give us the file in both cases.
I already have a video player that works the way I want it to work. Same thing with e-books and audio. (Having an app to manage the library of media is convenient once the collection gets larger, but I'll choose the app myself.)
First thing something would do with this: integrate it with Google Glass. While nodding your head or tapping a touchpad on the side by your temple might be awkward, discretely swiping up and down with your had would be more natural and less obvious.
> Apps ought to provide some actual functionality, not just blobs of content wrapped up in binary files.
I completely agree with this. I've downloaded some apps for blogs on my phone, but I realized that they just sit there in a folder, on a home page a rarely visit, while my RSS app is front and center in my dock.
