This guy isn't an idiot. To the contrary, he is exploiting the legal system, our society and one company and it's misguided marketing to make himself a killing. And what you all need to worry about is that it won't stop there. He probably waited on this opportunity and chose this particular case because it is easier to win over a jury and make a windfall with "they lied to you by 50%!" than "they lied to you by 10%!" If he wins, or even gets a settlement, his very next action will be to sue any manuf that has advertised storage space on computer equipment without having an * indicating that free space will be less due to X, Y, Z. He will start with the ones least able to fight and continue on to progressively larger and more profitable companies, probably hitting Apple when he believes there has been enough public mind-shift to win. For the rest of us, if 2 TB is worth about $100 (HDD) then 16 GB is worth about $0.80. That, times three, is about the absolute max that any of us might expect to see out of this class-action lawsuit and the subsequent lawsuits that are sure to follow. Meanwhile, this lawyer is likely going to ask the court for a paltry 10% of settlements plus legal expenses. 24 cents times a billion is still a very large amount. For PCs the amount will be larger (more SW / more bloatware). For Android and iOS devices the amount will be smaller. Either way, $250 m represents a nice retirement package. And what the jury won't grasp is that since lawsuits are all zero-sum games, all such settlements invariably derive from increased device prices paid by them. This lawyer is going to convince a jury to take dollars out of their very own pockets and line his with them. And they will do it thinking that they are somehow benefitting from the act (doing good for society against evil greedy corporations). What a mind-f***.
No, he's not stupid. Evil? Yes. A blood-sucker? Surely. An economic, moral and resource drain on society? Without a doubt. But stupid?
Stupid is the lawyer at MSFT who approved the marketing message for the surface, rather than rejecting it saying that it needed a strong disclaimer (or stronger than it has; I haven't looked at their marketing in detail).
