The point is people will not be seeing TB ports in low end devices like they do now with USB. Nothing about the port was designed to compete with that market segment where USB rules, which is low cost devices that plug into your computers.
Look at it this way I can select from hundreds of micro controllers to implement product "xyz" at very low cost. Finding similar hardware with PCI-Express ports or even TB built in is impossible. We are talking about devices where 50 cents in the price of the micro controller makes a big difference.
As to high end devices like RAID boxes and high speed audio video equipment, USB doesn't really compete well there either. When these devices do hit the market I would not be surprised to see a price premium due to the requirements for an upscale processor and the TB chip.
All of these concerns will obviously go away in the future when you can buy $5 micro controllers with TB ports built in. The problem there is I don't see a rapid move to supporting TB in the marketplace. In fact at the moment it appears as though Apple and Intel are keeping TB to themselves. Now maybe they have partners working behind the scenes to secure suitable silicon to drive the TB peripheral market, but honestly I would expect more by now.
Intel's including it on all of their boards and excluding USB 3. They don't need a compelling technical reason; it's being provided whether they like it or not.
They aren't excluding USB3 any more than anybody else. USB3 will be supported on Intel motherboards when it is in the system chipsets and not before. Intel can't ignore USB3 totally, it will fill a significant niche. They may not like it but in the end they will loose market share to AMD which will soon have USB3 in its chipsets. But again you miss the point, Intel can include TB where ever they want, the designers of peripherals need hardware to leverage to build the components to use with that TB port. In the end it is like Firewire, if you can not build low cost hardware, easily other ports will win out.
