> since you don't need to replace components

I think the fact that you have to manually add a component for connection by soldering, even if you can remove it later, makes that point somewhat moot.

Let's look at it from another point of view. The combination of needed skills is rare, and if you had to pay someone to do this, it would likely cost to fix it is more than the cost of a new device (since they would have to research how to fix and apply that knowledge. If there was an existing market you could easily tap it may be cheaper). If the cost to fix is more than the cost to replace, it's a brick.

I get your point, but if soldering is the only problem, just get a spring loaded solderless connector for JTAG pads? then it is about the same as USB for many more people?

I just think you'll have to go quite a bit farther to convince me that using a USB key fob in an existing USB port, which I can probably find and buy at a 7-11 down the street, is the same as acquiring a spring loaded JTAG pad or soldering a JTAG connection in place to a device I have opened to expose the circuity, and then configuring the software required to interface with it.

In one case, I plug a USB stick into a working computer, which virtually everyone has already done at some point before, run a utility included in Windows[1], and maybe download and drag some files around to copy them. In the other I do a whole bunch of stuff that isn't common to any neophyte or even most advanced computer users.
