Excepy BT4.0 is not a single standard which is why devices are DROPPING it for a single standard called wifi direct.... one single system... under one wifi direct logo...
BT 4.0 has many many systems and standards not limited to..
There is not one standard for BT and has not been for a long time... and as more "BT" headsets release more "standards" that are not supported get released...
Yet I have never found a bluetooth device my phone doesnt support, or that my bluetooth speakers were not compatible with.
The PS4 actually sees every bluetooth device I have tried to connect, including my phone yet it says "Profile not found"
So yeah it supports the standard everyone wants, its just Sony is not actively adding the profiles of standard devices like pretty much everyone else who wants to claim Bluetooth compatibility does, yes even cheap knock off stuff has much cgreater compatibility.
Its to the point where it cant even be incompetence, its purposeful locking out of devices to further a sales agenda IMVHO, and thats pretty rude, but its the Sony we know and love right?
Remember when the PS4 was announced to have universal in game music? And remember how the only way to do that was via Sony paid services?
Finally, the structure of my question is that you would have to disprove every possible outcome to be correct and I would just have to have one that would likely be beneficial. That's statistically in my favor by quite a bit.
Sony made some poor decisions with the PS3, and now also with the PS4. However most of the PS4 decisions are pure and simple. Keep price low, make more money than with the PS3, and avoid a hack like in 2011. Now add in some poor judgement by some at Sony and probably some examples of the Peter Principle.
Overall for me, and even missing features i wish it had, the PS4 serves me very well. The PS4 browser works well enough that my pc is seldom used for browsing and email.
