http://www.apple.com/shop/prod... is what I used to run Migration Assistant in TDM between a 2008 MBP (with FireWire) and 2013 (with no FireWire). I don't do that much A/V stuff, but is there any reason to expect it wouldn't work for your use case?
Thankfully my professional grade MacBook Pro docks with my professional grade Thunderbolt Display in the location I most frequently use a network port and would otherwise be port limited, and the display has a dedicated ethernet port. Everywhere else, I have my dongle, and really, I've used it at most 10 times in 2 years.
They may be medieval lunatics, but they seem pretty serious about enforcing a consistent (if deeply regressive) version of sharia, and in their eyes it's better to be a dhimmi than an apostate, and the reports I've read suggest they consider any Muslims who disagree with them to be apostates. I definitely wouldn't use the term "beneficence" to describe them (even relatively speaking).
At least with Daesh, you're better off as a Christian or Jew, where you can get away with surrendering and paying taxes, than as a "moderate Muslim", where you're likely to be declared an apostate and murdered.
How fast Apple abandons which hardware, exactly? We're talking computers here, not phones. My 6 year old MBP still runs Mavericks fine, and I just sold it for $500, because it's still a damn nice computer for the majority of users (8GB of RAM, 240GB SSD, and a 15" screen).
