I've been a long time Apple supporter, even going so far as to pay all the $$$'s for one of the late 2013 "trash can" Mac Pro workstations, shortly after it was released. (I did that only because I owned both a 2006 and 2008 Mac Pro tower before it, and both were excellent computers that I got years of daily use out of -- paying for themselves several times over with the work and entertainment value I got out of them. I figured I'd invest in the new direction Apple was taking things, with faith they'd make sense of what seemed at first to be kind of a step backwards in design and functionality.)
Well, unfortunately, what I'm seeing is a trend away from Apple catering at all to "power users" or "computer enthusiasts". Under Steve Jobs, at least their push towards minimalist styling/design was still well-balanced with giving the user what they really needed to get things done. (EG. When Apple declared the 3.5" floppy was dead and removed it? The rest of the Windows PC world thought that was crazy. Yet the advent of IOMega Zip disks, Syquest cartridges, dirt cheap CDR media, flash drives, SD and CF cards and more proved Apple was right. They were just pushing people a little further towards that "cutting edge" of tech, instead of sitting complacent in the middle of the "tried and true, but fading in usability" zone of technology. And when Apple decided to quit including optical drives in any of their systems? Again, some people threw fits but it's ultimately proved to be the sensible solution. External CD/DVD/Blu-Ray players and recorders are cheap and easy to plug in if/when needed, and they don't bulk up or weigh down a computer when you DON'T intend to use one. It also means when they break down, which they do fairly often with all their mechanical parts inside, they're easier to replace.)
With Thunderbolt? I feel like Apple tried, once again, to "skate to where they thought the puck was going to be" instead of to where it was. But that time, perhaps they took a chance and weren't quite right. Nonetheless, it wasn't really a big problem for users because it was only there in addition to plenty of other ports. The ability for Apple's Thunderbolt port to double as a "Mini DisplayPort" connector ensured people would use it with a dongle to attach extra monitors even if they never used it for anything else. And on higher end systems like my Mac Pro? It's actually quite useful since you pretty much need some kind of external drive enclosure to have a decent amount of storage space directly attached to the machine. There are a number of good options for multi-drive cabinets with Thunderbolt connections, and it provides great throughput without bottlenecking a USB bus.
But now, I feel like options are getting deleted just because Apple would prefer to have fewer configuration options to stock in their lineup, or because they're pushing change just for the sake of being different. (That whole elimination of matte vs. glossy displays is a great example, even if it still happened under Steve Job's watch. There was clearly a LOT of demand for anti-glare screen displays, yet Apple simply ignored it and told people "Tough luck. We think you'll love our product enough to buy it anyway, so we don't care.")
This move to USB-C? I think the new standard is just fine for netbooks or "Ultraportables" where people are primarily concerned about how light and thin it is, and probably don't WANT to connect very much up to it. But it definitely has no business in a Macbook PRO laptop being sold any time this year ... Not unless it's just there in additional to a couple of regular USB 3.0 ports. Otherwise, you're ignoring a universal standard that has no signs of dying yet. Go shop for a new inkjet printer and tell me how many have USB-C connections on them vs. traditional USB right now. Same for any digital cameras with connection cables.)
Secondarily, I agree that this change means eliminating a connector (mag-safe) that really does offer a great feature that competing laptops never had. IMO, if Apple really wants to move things forward again, they should create a laptop that inductively charges from a charging transmitter that you place anywhere in the same room with it. Moving it to charging via USB-C is a step sideways, if not backwards.
