I read most of the post in this thread, and I must say there is a lot of nonsense. Here's a summary with analysis of what most of you folks have been saying...
1) The 2015 MacBook is THE FUTURE, and sometimes we need to carry folks kicking and screaming to that FUTURE.
REALITY CHECK: Is 480p video, a very lackluster dual-core CPU, limited RAM/HD options really "the future"?
2) Why couldn't Apple make a MagSafe version of the USB-C connector?
ANSWER: Because it wouldn't be an industry standard USB-C connector now would it?
3) Why differentiate it as "MacBook" from the AIR and PRO?
ANSWER: Because if the MacBook line flops, you still have the AIR and PRO. Apple is playing it safe by breaking notebooks into 3 families.
4) Why are we all here reading, commenting and complaining?
ANSWER: Because we all still want something more than Apple's current offerings, and we hope that a new machine will satisfy at least some of our wants. But the new MacBook dissatisfies about as much as it satisfies.
5) Is a missing SD Card slot really "The Future"?
ANSWER: Although Apple wants us to pay for iCloud photo storage, that will not replace your camera which uses an SD Card. When on a shoot (as a non-pro, shots of my kids), I may want to remove the SD and plop it into my spanking new super-portable computer for a quick check. And yet, no one wants a dongle to accomplish that. You would be better off with a MB PRO in that case, which is rather silly because parents shooting photos of kids are NOT Pros, we're more of the el-cheapo audience that Apple hoped the MacBook would appeal to.
6) What is THE REAL FUTURE of Apple NoteBooks?
ANSWER: As a few wise people in this thread have mentioned already, WIRELESS CHARGING. Apple will ultimately need to severe all cords entirely. Even so, I still think that "memory slots" (for SD cards) can and should survive in such a "wire free" future. SD cards with WiFi aren't a perfect solution for everyone. Furthermore, as long as some flavor of WINDOWS exists, we Mac users may need to have the necessary ports to access devices and content used by our cable-loving friends from Redmond. Therefore, a truly wireless future (Windows included) may take another 20 years. That's a long wait, folks. And Apple ditching ports isn't necessarily going to speed that process along like it did with the death of the floppy.
7) So what should we all do that this point?
ANSWER: We should be eagerly awaiting a Skylake MBP and hope all the ports and slots are still there, yet a tad lighter, thinner, and with better battery life, and selling at a lower cost than now, reflecting the industry-wide decline in FLASH MEMORY prices. Throw in a MBP "gold" option to tickle us pink, er... gold. It's not like we're going to get our gold fix on the Apple Watch!
