You can scout the whole of the intertubes, but you’ll be hard pressed to find a biggest sense of entitlement than that of a certain “David S.”, Dropbox customer.
In a tedious, autistic, monotone, comment after comment, the guy rants against the Dropbox team for not launching a “release” version of their client.
Mind you, he raises no specific quality issues with the development builds, except of the fact that they are not “release builds”, as if an arbitrary version tag makes all the difference for the user of a software.
If you are easily amused, and have 10 minutes to spare, go through the thread, it’s quite entertaining.
