I really wish someone sue the disk/USB/Smart media manufacturers on not giving all the 16 GB they promised me on the package. It clearly says 16 GB, but when I shove it in the computer says 15.2 GB available space.
That is hardly the proper analogy.
The disk space lawsuits (which were settled by WD back in 2006) were a consistency problem with naming due to some companies using binary naming and some companies using decimal naming. Binary naming was favored by Microsoft and decimal name favored by disk manufacturers.. which they still are.
Logically, a KILObyte would be 1,000 bytes, right? Microsoft instead decided that it would be 2^10.. 1,024 bytes instead... and that has been the standard ever since.
A true 16GB disk according to Microsoft (and everyone else) would be 17,179,869,184 bytes..
In binary that is 16GB, in decimal that is 17.179GB
A true 16GB disk according to storage manufacturers would be 16,000,000,000 bytes.
In decimal that would be 16GB, in binary that would be around 14.9GB
Now, with the range it is not a case of binary vs decimal, nor is it a case of the anti-brick buffer, as the 60 kWh pack is 61.6kWh.. logically the 85kWh pack should have been slightly higher to be consistent, but it appears someone in marketing decided that saying 85 was better than the 80 it should have been.
However, the packs all had corresponding EPA estimates, so this is just a case of mistaken marketing, rather than malice.
