Calling Thunderbolt a failure, even though I get where you're coming from is to ignore history. Firewire is not a new technology, it's had over a decade to get its current level of support. Furthermore even though FW did quite well in the Digital Video Camera market in the early days, as computing accessories went it's NEVER been a mainstream technology.
Wanted a Firewire HDD Enclosure, a FW Card Reader, FW DVD Burner? Good luck with that (they exist, but try finding a physical store with these in stock). Wanted a Firewire Hub? Well, it used to be easy, Mac stores had them available often but these days? Not so common.
The only thing that has been easier with FW was buying an external HDD (not just an enclosure). To add to that, if you found any of the other items mentioned, till the last 1-2 years the 'premium' you'd pay for them would often be significantly more than the USB 2 (+ eSATA) alternatives. I personally have bought most of these things, so I know from first hand experience what's been required to research / purchase them.
So where Thunderbolt is now seems like a parallel of where Firewire previously has been.
So now I have two thunderbolt ports, I use them to connect at times to my external display via the MiniDisplayPort (which has been around for some time now and is well supported) using the Thunderbolt port, connect the one Thunderbolt HDD I do own (which cost a fortune, but also gives me performance my FW800 HDD could only dream of) and to connect my FW800 HDD drive+FW Card Reader via Apple's FW-to-Thunderbolt adapter, which I daisy chain. Even if I had a display which utilised a FW interface, I could still add it to the end of my FW daisy chain and i'd be fine.
If my thunderbolt HDD supported daisy chaining then i'd be able to connect all of these at the same time without issue to my Mac, unfortunately it doesn't, but that's hardly Apple's fault (it's LaCie's). As such, I'd like a Thunderbolt hub, but I'm holding out for now till there is something that isn't the kitchen sink offering but a good old fashioned multi-port hub. The lack of this is Intel's fault, not really Apple's, Intel is the one licensing it, Apple chose to use the technology, so they hold some responsibility, but they don't set the licensing fees or conditions which places Intel as the primary problem here.
xgrep's requirements can be addressed if his monitor uses a FW interface as it could sit on the end of a FW daisy chain and presto, problem solved. If he has two TB ports, then one port will cover his FW needs (daisy chained again) and the other can have the display attached (and should he later buy TB devices, he can create a TB daisy chain with the monitor at the end of that too). As for eSATA though, well, Apple's never catered for that, it is frustrating, but it's not something new.
