The Release Early/Often example describes a situation of releasing a product that does not have all the features of its competitors: "The Windows Operating System, in the initial version (1.0) did not support overlapping windows which was a breakthrough feature on the then contemporary Macintosh."
Identically, the Polished Release example also describes a situation of releasing a product that does not have all the features of its competitors: The first version of iOS "(then called as iPhone OS), did not even have MMS"
Seems like the author didn't pick a great example to demonstrate a Polished Release.
His example outside of software[1] is not the best either. Movies do have "versions", they are called cuts; an example of multiple published cuts for a movie is Blade Runner.
[1]> Every single release of a movie, whether it is The Jurassic Park and its sequels or The Matrix and its sequels or Steve Jobs’s own Toy Story and its sequels never had "versions".
I've been using it for ~6 months and have never encountered any limits, file size or bandwidth.
It is open source too: https://github.com/glenmurphy/dropmocks
