I don’t think nor say USB-A is obsolete, but not blind to the writing on the wall.
It's going tp be a while before USB-A goes away totally, and even longer before every new peripheral actually uses 20/40Gbps USB4 or TB4 and won't work perfectly well from a USB-A port.
As I said, I'm not particularly concerned if USB-A and other "legacy" ports get swapped out for the same number of USB-C ports - the problem is when USB-A, Ethernet, HDMI, power etc. ports just disappear and everything that used to have a dedicated port has to go through a handful of USB-C ports,
And yes, it’s potentially “now only five”, but it can split and multiply… could make that potentially 20+ total if all of them happen to be Thunderbolt compliant. Or daisy chain them for supporting gadgets.
Except that is still a "downgrade" from having enough ports on your
desktop machine for your needs. First - lots of extra boxes, wires and probably wall-warts. Second - more to go wrong. Third - splitting a port 4 ways doesn't give you 4 times the bandwidth.
What's the point of making a Mini extra small if it means you just need more external boxes?
I also suspect that a lot of people don't really understand how USB 2/3 work with USB-C. If you plug 4 USB 3 (whether its A or C) devices into a TB4 hub they're not sharing 20Gbps of TB4 bandwidth - they're sharing 5Gbps via a hub - it's actually no different to plugging 4 USB 3 devices into an old-school USB hub - with the same potential latency and compatibility issues, (I'm aware of
one TB3-to-USBA product that actually has 3 PCIe controllers to give you 4 top-tier USB-3 ports - a few TB3 docks have internal host controllers, but typically driving internal hubs and shared between various interfaces, SD slots etc. - but the 'USB4/TB4' way is to use USB tunnelling to connect a USB 2/3 hub to the computer's internal USB controller). Same with USB 2 devices - everything on the hub is sharing just 480mbps of bandwidth. TB4/USB4 hubs only give an advantage if you're going to run actual TB/USB4 or DisplayPort devices alongside your USB ones.
I've got plenty of USB devices where #1 in the troubleshooting guide is "try connecting directly to the computer without a hub".
One of the problems with USB-C is that it didn't really make things
better for USB2/3 devices, and actual 20Gbps devices
still carry a hefty premium - you just got to buy new dongles and cables. Plus, unlike the bad old days of RS232->USB 1 -> USB1.1 -> USB 2, USB 2 and 3 are increasingly fast enough for many purposes.
haven’t bought an external USB-A SSD (or any Lightning gadget for that matter) in some years now.
It doesn't matter what the connector/cable on the SSD enclosure is - all but the highest-end SSDs and multi-device enclosures use USB 3.1 protocol and will work just as well on a USB-A host port (the only snag on Macs is that Apple doesn't support 10Gbps over USB-A, but that's either Apple's choice or down to a lack of I/O lines from the processor).
USB-C ports are becoming popular on peripherals because... well, you know what a Micro-B USB 3 connector is like - but it's still the same old USB 2/3 protocol and, unless it was from a manufacturer that only targets the Mac market, betcha it came with a USB-A cable or adapter in the box.
Personally, I still use spinning rust external drives for additional backups/archiving - and there's
no point having anything better than USB 3.0 on those - but it
is useful to have a free port from them.
There are a
lot of current low/mid-end "prosumer" audio production equipment, instruments etc. that only use USB 2 (a CD-quality audio stream is only about 1.5mbps - so USB 2's 480mbps is plenty and will happily run a 16 channel audio interface) - in fact, MIDI-over-USB only needs USB version 1... Implementing USB 3 (let alone USB4) would be a waste of money, and USB 3 can also cause radio interference issues. What these devices
do like is - wherever possible - being connected directly to the host and not via a hub (
Example - has USB-C port but comes with USB-A cable).
Apple pulled USB-A from their laptops years ago
Which is probably why the market is flooded with hubs/docks that are purely designed to give people their old ports back.
Also, don't forget that Apple pulled a U-turn and brought back the MagSafe, HDMI and SD card slots on the MacBook Pro. This isn't just about losing USB-A, it's about being forced to use fewer ports.
It's also interesting that, since the all-USB-C MacBook Pro was launched, only one desktop product has gone down the all-USB-C route (the 24" iMac) and everything else (5k iMac, iMac Pro, Mac Pro, Mac Studio, Mac Mini) has kept it's USB-A, Ethernet (and HDMI, SD where they were there to start with) ports.
This rumour is good in one respect - it keeps the internal PSU, HDMI and Ethernet. Front-mounted ports are nice... except they come
at the expense of rear ports. Now, personally, I'd keep the front port for things that I regularly plug/unplug like memory sticks or secondary backup drives, and keep permanently connected stuff plugged in at the back with the cables out of sight. Unfortunately, the reasoning here seems "we want to make it smaller because form-over-function so
two of the existing ports have to move to the front"...
