They removed the MiniSD card slot from previous generations. Let me guess, those slots will only be on "Pro" Macs from now on? 😡
The dumb thing Apple doesn't realize... is that... a typical $1600 iMac is something that many many Mac users use as an archive and a "backup" for their iPhone photos, iTunes and other data, their Nikon DSLR images, etc. Sure, there is also iCloud. But the Mac (with its terrabytes of storage) is a very convenient place to back up everything from your portable devices, digital and analog cameras, etc. It's also the place where serious photo/video editing happens once you transfer photos from your cameras and phones.
By removing the card slots, they made it less "photography-friendly". Oh right, but someone is going to tell me "Oh but you can just buy a dongle/adapter!"
