Even cameras are starting to move away from SD cards. It's convenient but doesn't really make a lot of sense to have such a specialist slot any more. Better to have a general purpose slot and a thumb sized adapter in your wires pouch.
I understand if you don't use it, but the point is, Apple removed it (in part) in their blind pursuit of "thinner and lighter", taking away a convenient port that many found useful. What harm would it do to keep it? Apple:"But that would make it .2mm thicker and .034ounces heavier!"
The MagSafe connector was always a marketing thing. Again, nice to have but not really the basis for choosing a laptop.
I disagree. It wasn't marketing - it was super useful! Besides the benefit of preventing laptops from being pulled off of desks when someone walking by snags the power cord, it prevented the heavy wear that occurs on rigid plugs that get torqued and bent from heavy use.
Overall, these and many, many other feature degradations at Apple are a result of not really knowing how to make products that "just work" anymore. (Hate to bring up comparisons with Steve, but it's true - he had a vision of user-centered design in a sublime package). Tim is just your ordinary businessman, not a visionary. You could pull him out and replace with any exec from Microsoft, and you'd get the same trajectory for Apple.
