to call the write-up underwhelming is to be the most generous one can be. the minimum requirement that qualifies one to add 'unpacking' to title wasn't met. this all reads as a poorly argued opinion of something google is apparently trying to force down our throats. the specification isn't discussed (they're generous to point you to it though), a cursory mention of the supposed pros are mentioned but an even lazier attempt is made at describing the cons. really disappointing read!
