I just blogged about this - that the limit of the 'free market' is that 'choice' is constrained by backroom deals and corporate self-interest. Sony put a Blu-Ray drive in the PS3 to create another revenue stream. Warner, Best Buy, Netflix et al accelerated the end of the format war to try and mitigate slowed growth in DVD sales and end consumer hesitation about HD discs. Companies, as they always do, were looking out for their bottom lines. If HD disc sales take off (while they'll never match DVD, they might still become a profitable business) then the fact that we'll be buying Blu-Ray discs will not be a result of the 'market having spoken' but will be another example that displays that the 'free market' is as much dictated by vendor/manufacturer interests as it is consumers' desires.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
