Just making a bit fun (with some serious undertone), but why would you offload media to a dead slow SD-card that only holds 128Gb? 30-40 films and you’re out of space again.
...because adding an SD card is a lot cheaper than buying a new Mac to get a larger HD, and - unlike an external HD -
preserves the all-in-one portability of your laptop. Most people have some bulky files that they need access to but which don't really
need super-fast storage - a media library being the most obvious example.
Sure, its not a solution to every storage problem, and if you need extra highYour logic seems to be "I don't need this feature - so nobody needs it and it should be removed with extreme prejudice."
If you’re more permanent away from the internet, e.g. you’re staying weeks at your cabin in the woods
You've never been on a 10-hour flight where the promised in-flight WiFi didn't materialise or cost silly money? Never been on the train where the cellular signal vanishes as soon as you leave a built-up area? Never been to a business meeting where nobody can work out how to get you on to the WiFi? Never worked somewhere where your WiFi connection drops every 20 minutes an the PC-centric support staff couldn't care less because Mac?
Anyway - I have a music collection built up over the years from CD rips and music purchased as MP3 downloads, so why would I want to stream that?
Yeah, all nice, but there are hardly any serious devices that use microSD
Well, yes, I'd agree that full SD would be more versatile than MicroSD - but if you're paranoid about your laptop getting a few mm thicker, MicroSD would be a compromise. As has already been noted several times, MicroSD cards often come with SD adapters that make them work in any SD device and are actually easier to store and handle when kept in the adapter.
As for "serious devices" - really? Not everybody who buys a Mac lives in an Apple-only walled garden. MicroSD cards are incredibly useful in the Android phones that support them. SD (which can easily be a microSD in a SD adapter) is pretty much standard in still cameras, pro video cameras, GoPros, dashcams, drones, audio recorders etc. My Amazon FireTV has a MicroSD slot. Plus, there are
over 12 million Raspberry Pis out there - not to mention other micro controllers etc. that use MicroSD cards. You know, exactly the sort of gadgets that a "prosumer" user who blows $2000 on a "pro" laptop is likely to have a cupboard full of.
The dongle discussion is rather funny. People want Ethernet, HDMI, DisplayPort and what not in their laptop. that makes the laptop a bit bigger and 10-15% thicker.
Yes... like the 2015 retina MacBook pro which was just too big and brick-like
said absolutely nobody ever at all (except, apparently Mr Cook who doesn't see why anybody would need anything bigger than an iPad and Mr Ive who is more interested in making art than making tools). If the ultra-tiny 12" MacBook with a single USB-C port fits your needs then that's great - but it doesn't fit everybody else's needs.
As for ethernet - guess what -
yes I stlll need it (see above re. reliability of WiFi at work) but we've had since 2012 to get over that. However - quick history lesson: when Apple dropped the ethernet port, firewire and optical drive from the rMBP in 2012 they
(a) added an extra TB port
and HDMI to the rMBP while keeping the power and SD ports and upping the USB ports to USB3 - so you had two ways of hooking a TB-to-Ethernet or Firewire dongle that didn't use up your only fast data port or external display connection; and
(b) at the same time
they updated the 'classic' MBP models to the latest CPU/GPU and added USB3 and BlueTooth 4 etc. so that, if you
were still dependent on Ethernet, Firewire or the optical drive - or weren't ready to fork out the premium for all-SSD - you weren't left high and dry without a replacement option (ISTR the 15" cMBP hung around for about a year, the 13" stayed around for years).
c.f. 2016: courageously, they kindly kept around the least-powerful model of the 2015 MBP - which was already overdue an update -
at a higher price for a perfunctory few months. Of course, if they'd repeated the 2012 routine and updated the CPU in the old rMBP at the same time, it would have been
very interesting to see how the new 2016 model sold...
