to plug in what though? most people, i've seen, are using the built in pci for usb3 and gpus...
If I were to generalize, the PCIe card -based complaints I've been seeing tend to be either music-oriented or high end video.
...as in, they're literally adding things to their computers which then require more cables to be plugged in to.
Yes, there's always going to be something else plugged in at the far end. However, what this change really represents is a change,
From:
(Mac Pro w/PCIe Card) <---cable--> peripheral
To:
(Mac Pro) <---TB---> (PCIe Adaptor Box w/PCIe Card)* <--cable--> peripheral
where * denotes the possibility of an additional power connection
Granted, we can assume that some of the vendors who are currently making their product available as PCIe cards can repackage them as TB boxes, which means that the
future anticipated capability can be illustrated as:
Future:
(Mac Pro) <---TB---> (speciality box)* <--cable--> peripheral
where * denotes the possibility of an additional power connection
ok.. so 1 extra cable and (assuming) one extra power plug.. granted, it's not cool to have to add more cables into the mix of anything but i think this scenario is livable..
Sure, it is "livable" ... but the question really is more of if it still represents a reasonble value, hence the
Thunderbolt Tax parlance. Add to this the complexities of product lifecycle variations and release dates and an ugly transition period (of presently indeterminate length) is assured. In the meantime, while "+1 Cable" doesn't sound too bad, that's in many cases a "1+1", which means two and thus a doubling of connections.
i'm interested in hearing an example (a real honest example) outlining 'cable hell' because of thunderbolt.. i mean, as far as i can gather, if someone is going to have a cable nightmare with thunderbolt then they already have exactly that without thunderbolt.. (edit-- or not thunderbolt per_se.. more to do with not having an all-in-one machine)
YMMV as to what the threshhold is for how many cables cross over into Hell, but as one can see by the above illustrations, the number of cables to support
N Peripherals is likely in a lot of cases to double, to
2N...and that's before considering the potential for additional power feeds (and a risk of
3N).
