You know, sometimes it's the "little" things that count, especially when you add them all up: the Apple chime (not "needed", but uniquely announced "Apple Here"), the lit logo (ditto), magsafe power port and connector, USB ports, SD card port, 3.5 mm phone jacks (still around on the Macs and iPads, bye bye iPhones), user replaceable batteries, upgradable parts, smoothly functioning keyboards, superb customer service. Mostly little things - now gone - all add up.
- No apple chime is awesome. you know how many times that chime has interrupted meetings or woken up my wife? Too bloody many! My iMac still does it (still on Sierra) and if upgrading to HS gets rid of it, I will do so tomorrow.
- I love the lit apple logo, but I never look at the back of my computer when using it.
- Magsafe... love the magsafe, but at the same time it really annoys me that I can't plug the computer in on the right side. Could be just my use case but this situation has happened way more often than you would expect. So losing magsafe but gaining that flexibility is at least a silver lining.
- USB port... yeah, until everything gets native USBC port cables, this will be an annoyance. Although about the only thing I plug into my computer now is the back up external HD. No worries there, but I often use a work printer which isn't wifi. That will be a pain. I'll need an adaptor.
- SD card. never used that slot, but I guess some do. If you do, that's not great.
- 3.5 Headphone. It's still there on computer. I think it's great them taking it off the iPhone. you still get wired headphones, but really, the AirPods are awesome and using the iPhone with them is so much better. It's a night and day experience.
- upgradable ram and battery. Battery sucks, and it would be nice to add more ram later, but in saying that, back in the day when computers became outdated faster, it was more important. I remember when my top of the line BTO titanium MBP (or whatever it was called) got to 3-4 years old, it was old. But this 2013 MBP top of the line I'm using now is still running totally fine after almost 5 years. Doesn't feel old or look old at all.
- keyboard. that seems bad.
- Superb customer service. I'm yet to get bad customer service with an Apple Computer in Japan. It's only been great. iPhone and iPad is a different story.
