Over the years, many features have disappeared from one or more iMac models:
1. Expansion slot (The mezzanine slot on the original iMac)
2. Reset/interrupt buttons
3. I/R port
4. Modem port
5. FireWire ports
6. Power/sleep indicator
7. Easily accessible power/sleep button
8. VGA port
9. Front speakers directed at the user
10. Easily expanded memory on all models
11. Optical drive
12. User replaceable hard drive
13. Side mounted ports
14. DVI port
15. Tilt/height adjustable keyboard
16. Industry standard hard drive without a wonky thermal sensor
17. Disassemble without need of a tape and glue kit
18. Matte screen
19. Fan-less operation
20. Number pad on the included keyboard
21. Audio input
22. Keyboard with real keycaps instead of Chiclets.
I'll guess that Apple will drop the SD card port along with user accessible RAM on all models. The excuses, if any, will be lame. Hey, Apple will just sell you an SD adapter, or more high priced memory up front. The Ethernet port is also a candidate for elimination, at least for the lower end models. And perhaps the four USB ports could be reduced to only two. You can always get a hub.
But rapture and joy, the latest iMac just might be a half millimeter thinner!
Nice troll. You repeat several things to pad out your list, and include things that haven't actually gone away - you're counting the change video adapter connector as two separate "negatives" despite the fact that the current iMac still supports both DVI and VGA output (simultaneously on a 27"). The iMac has never had a user replaceable hard drive (the candy drop ones didn't, nor did the sunflower which was a pain to work on, nor did the Intel ones - white or unibody).
The RAM has got *easier* to install on the 27" unibody iMacs compared to older ones.
The power switch is not easily accessible? Do you have hands? That is possibly the most nonsensical complaint I have ever heard.
Oh, and the older style keyboard still totally works with the current iMac. You should try it, since you seem to hate the current keyboard enough to make it about 3 different points on your list.
Also, dropping the POTS modem is a major downside? What is this, 1995?
Man, with list writing skills like this, Buzzfeed will snap you up. You should send this to them with a pseudo-catchy title.
