Because you can't plug a SD card into a TB3 port without having a dongle hanging off your laptop
But you can
do it. As opposed to if we have an SD card slot that.. what? 20% of Mac users might use? and the rest just have a port they'll never use, and which can do nothing else.
Because SD and micro-SD cards are by far the most popular format in consumer/prosumer DSLRs, camcorders, phones, dashcams, sports cameras, maker boards (RasPi etc.)
I've used computers since I was about 7 or so, at primary school. I bought my first computer while I was at high school. I worked in an IT department supporting lecturers and tertiary education students across a dozen campuses.
I don't believe I've ever seen anyone not
just plug the camera/what have you into the computer to download photos, until
I bought my wife a low end Canon dSLR several years ago, and she imports the photos from the camera to her phone over wifi
Unless you can show me some kind of statistics about actual
usage, I'm fairly confident SD card slot usage is like the floppy drive still on some PCs. Sure it can be used and some people probably do, but it's inclusion is not indicative of actual use.
Because, for many of us the convenience of having the dedicated ports we need built right in to a laptop outweighs the theoretical benefit of having more potential TB3 bandwidth than the thermally-constrained processor could ever cope with.
But this is my whole point. Which dedicated ports? Because almost every dedicated port people whinge about, it is very much dedicated to one very specific task, and can'd do anything else, so if you dont have that use-case, it's worse than useless, because your argument is that it's desirable to give up some universally compatible ports for some ports that you personally find useful.
Why is having 2-4 Thunderbolt ports (one of which you have to "waste" on a laptop by plugging in the charger) soaking up all the CPU's i/o and video output capabilities "in the best interest of the majority of users" when USB 3 is fast enough for most people?
You don't have to waste anything. A $25 USB-C (not even TB3, so it'll even work on the 12" MacBook) bus powered "hub" will give you 3x USB3, HDMI, SD, TF and has 100W power pass through
. FYI this is already more ports than all the "single purpose" ports on a pre-TB3 MBP.
It's in the interest of the majority of users, but more users can achieve the connectivity they want, via TB3 than without it. A TB3 port can become any other type of port on the market today. Any of them. You need a cable or an adapter, yes. But as mentioned twice now, you can literally provide more functionally than all the "dedicated" ports of the pre-TB3 MBP with a single $25 hub, without forcing that combination of ports onto anyone else, nor being forced to live with any other single-purpose ports that you
might not have a use for.
Which adapter do I need to buy to make a SD card slot connect to an eSATA disk array? Gigabit Ethernet? How about DisplayPort? How many devices can I daisy chain from the SD card slot?
Are you seriously telling me there are people who carry around a MBP and a digital camera - even if we exclude/ignore the charger or additional camera batteries/lenses - but a hub the size of a mars bar
is too much to handle? Give me a ****ing break.
Why - 4 years after Apple went USB-C/TB3 crazy - are manufacturers still releasing new USB-C and TB docks that, basically, replicate the 2015 MBP i/o ports? Not because that's what the majority of people actually need, surely?
people use some
of those ports? Just like some people use all the other variety of ports that appear in TB3 docks/breakout devices? HDMI, DisplayPort, eSATA, Firewire, Optical audio, numerous other card formats, gig and 10gig ethernet. I'm not sure how you see this as making a point for your argument. Are you forgetting that the $25 USB-C hub I have mentioned several times now, has more "single-use" ports than the last non-TB3 MacBook Pro had, and it's the size of a ****ing mars bar. No one ever said "no body uses these ports". But plenty of people seem to be arguing "nobody needs anything besides these ports, and even if they did, **** them, my SD card slot limited to USB2 speeds is more important"
was a solution looking for a problem
Right because no one ever wanted to use an external device that works quicker than USB3, or operate using PCIe lanes directly. How silly of me. I'll just go plug a GPU into my USB3 port and see how well that works.
they really are a small minority of users
But people wanting to plug an SD card directly into the laptop aren't a minority?
