What's wrong with eSATA/SATA/PCIe/USB/other existing technologies? I don't fault Intel for wanting to try their chops in the data transfer tech market but it's saturated enough as it is and real high end computers will make use of eSATA/SATA.

Thunderbolt - all of the versions - can be summarized as "External PCIe". It's just that ePCIe isn't nearly as marketable a name as Thunderbolt.

It's not. Thunderbolt is a very very closed standard by Intel. With standardized protocols, like regular PCIe, to start building a device, getting started is pretty much a case of ordering a few chips, reading the datasheets, and starting up in a design program. Thunderbolt, on the other hand, in order to even start looking at the datasheets, you have to apply to the developer program, and wait an unknown amount of time for intel to decide if you can even start to develop. Once your device is ready, you have to wait again for intel to approve it, and there is a chance they won't -- the first Thunderbolt GPUs were promised 5+ years ago, but Intel wouldn't approve for them being sold.

That sounds excellent. Fewer amateur hour broken, incomplete and potentially computer damaging implementations!

That they are all multiple specifications to bother with (you mentioned 4+others), and that they don't offer the full capabilities, speed and power draw TB3 does. Not to mention the ugly cabling.

>and real high end computers will make use of eSATA/SATA.

There's nothing unreal about a pro wanting an expandable portable compute to function as high end.
