Originally posted by stevebrot I just keep the card reader in the computer at all times (built in) and simply flip the card door open, take the card out, and put it in the reader for full USB 3 speeds without having to fiddle with the clutzy USB 3 connector, the rubber flap, or tripping on the cable (flings the camera off the counter...not good)...

I agree, I exaggerated the cable-way and you the card-way. I do understand that there are good reasons for not including it, although I don't know why, I suspect some of the mentioned reasons such as time to change it, space for the connector or similar are the reason.
But for fun, let's at least try a more unbiased/fair comparison: (Help me add factors for and against each here, I use cable mostly and may not be aware of other card advantages or disadvantages)
Points: Team card / Team cable
0/0.5. Buying a good card reader. 1 or perhaps half a point to team cable - the cable is included in the box and free so no time or money spent on getting a good usb 3 reader.
0/0.5. As you said, the reader can be attached/built into the computer as well as me having the cable connected at all times so we call finding cable/reader a draw.
0/0.5 Flipping card door open vs cable door draw as well.
0/0.5 Ejecting the cards vs inserting the cable also similar effort. Cable is a bit more fiddling perhaps but there are two cards vs one cable on the other hand.
0/1 Putting the card into the reader, 1 point to team cable? Let's say just a half, it's a minor thing.
1*/1 Transferring images, a held point for team card here - this is what the discussion is about - it wouldn't be any faster using the card if USB 3 was used for the camera connector.
1*/2 Waiting for the transfer from card 1 to complete, eject it, put the other card in, resume transfer on computer OR don't wait for it and "lose" the time it didn't transfer while away, and replace it when coming back - either way I'd say a point to cable
1*/2.5 Take the card out from the reader AND put the cards back in the camera and close the door vs just pull the cable and close the door. I would have let this one slide if the possibility of forgetting to put the cards back wouldn't mean problem/delay at next shoot so at least 0.5 I'd say.
1*/2.5 Card reader ejector wear vs connector wear..tie?
1.5*/2.5 You mentioned the risk of tripping the cable..camera sitting on the desk? And also someone mentioned a few minutes more battery drain. I'd say the first risk is really small, and the second one also not worthy of a point since you'd probably recharge after a shoot anyway, could it be a few % of the charge at most for a large transfer? But I can be nice and give 0.5 to team card for them combined not to seem unreasonable =)
So 1.5p for cards vs 2.5p for cable, even though I think I rounded to the cards advantage at a couple of places and one point is considering usb2, not usb3
So I'm not after starting a transfer war here =), I realize different parts of the above would "score" differently for everyone, but I just wanted to show that the view "why on earth would anybody care about the usb connector" isn't a great one, I still believe the card way is more convenient in most cases, especially with two cards (which I guess would be needed to maximize the possible write speeds and empty the buffer as quickly as possible).
But if I could choose =), I'd want 802.11 AC -compliant wifi transfer instead, which I think would win the comparison above...perhaps half the speed of usb3 but then NO fiddling with camera doors, readers, cables etc..
