Is that a RIM Micro USB cable? So the unit didn't come with one then? Or they shipped it with someone else's cable? Come to think of it, there seems to be a lot which was promised from Retro Computers that doesn't appear to have arrived. 986 games, among other things apparently.
So, the real question: Are they intentionally ripping off their backers (they aren't really customers, don't forget, unless a judge says so) or are they really that sodding useless? "Never attribute to malice that which can be adequately explained by stupidity," so goes the phrase, however with the caveat of "but don't rule out malice". I truly do wonder which it is.
