And there is not a Mac that Apple sells that isn't so compromised that I would consider it worth its asking price.
Great looking computer, would buy them for my kids or to take on trips, but a single USB-C connector and a 1.2GHz Intel Core m5 do not make for a general purpose computer. At some point, somebody is going to have come with a single cable replacement to Thunderbolt that will drive a 5K monitor. Until then, I'd feel like I was buying a disposable machine.
MacBook Pro 13-inch
Yes, Apple is still selling the same MacBook they sold me in 2011, more or less. It did manage to pick up USB 3.0 ports. Can put an extra hard drive in it. But 802.11n WiFi? 1280×800 screen? I already have this excellent but out of date machine.
MacBook Pro Retina
I use one for work, and it is a great machine. Plenty of ports. Beautiful display. Great trackpad. Adequate keyboard. MagSafe connector. Solid as a rock. I guess I could see getting the 13" model. But to be my main machine it would need a lot more that 1TB of storage and unlike my 2011 MacBook Pro, there's no place to put an extra drive in it. Plus, why is the 15" $700 more than the 13"?
Who, at this point, is going to buy a MacBook Air, with its ridiculously out of date screen?
The 5K Retina iMac is actually quite a nice looking computer, but I just cannot get around the idea of permanently tying a desktop Mac to such an expensive monitor. Also, a desktop Mac with pretty much zero internal expandability. I used to own a PowerMac 7600, now that was an expandability monster. Maybe if it were cheaper.
I could buy one if I needed the performance level, but I'd feel foolish given how it hasn't been refreshed in 3 years and still has an entry level price of $3000.
The current Mac Mini is a compromised product crippled—I would guess—to keep it from taking sales from higher margin machines. I feel bad for the engineers tasked with taking the epically nice 2012 design and removing all traces of internal expandability or quad-core processors. I feel bad for Phil Schiller for having to introduce it. I feel bad for anybody who paid full price for it. I feel bad.
The Buying Trigger
I'm happy with my Mac Mini. In order for me to get out my credit card, a Mac would have to do something my current one can't. So, if there was such a thing as an affordable quad core 13" Retina laptop, with 2TB of storage, and it had a single connector that would drive a 5K display, that would be something I would buy on the first day of availability. Until then, I'd only buy a new Mac if an old one broke.
