Microsoft Surface Free Space
When I first learned that the 32GB model only had ~16GB free, I was surprised. I know they have verbiage that warns the user but when I read an article that discussed this, I knew it wouldn't be long before it turned into a black eye for them.
They should have only claimed 16GB, they should have included 48GB and claimed 32GB or they should have put the recovery stuff on an SD card (included with the unit) so more of the 32GB is free for customer use.
It's OK to reserve some space for a recovery partition when you have a 500GB or 1TB hard drive but not when you only have 32GB.
