In the end, the consumers will see none of it (who's really going to go through to paper work for a $3 rebate?), the lawyers will see millions, and the government will get the unclaimed payouts.
IOW, a complete waste of time.
The benefit to you as a consumer is that the next time you buy DRAM from one of those companies you can buy it with the expectation that prices are no longer being illegally fixed. In other words, you can expect memory to cost less than it would have if there had been no lawsuit. So, not a complete waste of time.
