I own the 2014 MacBook Air (fully loaded)
I own the 2015 rMacBook Pro 15" (base config)
I own the 2013 MacBook Pro 13"
I now also own two 13" MacBook Pro (base config)
SCREENS
The new MacBooks are superior. The difference is obvious against the Air, more subtle next to the older retina version. But the brightness of the newer display IS obvious, even if the color advantages won't matter to most. Winner-tMBP
KEYBOARDS
There's no point in going around in circles. A few will have an issue with any change in a keyboard design and this is a very personal thing. I type about 45 WPM and my wife is over 70 WPM. Both of us are able to type faster with the new machines. On the surface, the new keyboard is clearly better made with no wobble and no light leaks. Most will adapt, a few won't. Winner-tMBP
PERFORMANCE
The new notebooks are faster across the board. Period. Are they MUCH faster? Nope. But to call them slow would be to say that last years MBP was slow and it sure isn't. I bought mine to handle high-end professional photography, which it does with ease. Does it do it better than the older machines? Yup. Winner-tMBP
BATTERY LIFE
Sometimes 5 hours and usually 7-8 hours, but 10 isn't going to happen often. My 1 year old 15" is no better, often only giving me 6-7 hours at best. I really can't see any difference between them, but the Air clobbers 'em all for battery. If you're going to be away from charging options, the Air is the one to have (keeping mine!). However, with the USB-C charging, the tMBP can use a power brick. But that's cheating! Winner: Air
PORTS
There's no "real world issue" with the ports on any of these machines. Some will prefer the legacy port ease. Pro's like me prefer having more of these faster and more versatile USB-C ports. You're not going to be hampered by either system. Winner: Tie
BUILD
The build quality of the tMBP does indeed feel better overall. Winner: tMBP
SOUND
We all know that Apple hit a home run with the new speakers. I could care less, but a win is a win. Winner: tMBP
USB-C vs MAGSAFE
You can make a case for either, but I had to buy two replacement MagSafe units and the one on my Air is also wearing out. I'd love it more if I could just replace the cable on Magsafe. It's also on the wrong side half the time. We can also now charge off a power brick with USB-C. Since you can buy a MagSafe type adapter, the safety issue with USB-C is moot. Too many advantages for USB-C charging and so...Winner: tMBP
TRACKPAD
The added space on the trackpad, once you start using it for grabbing text and working PP on photos, is a real advantage. It won't matter to everyone, but it's still an upgrade. Winner: tMBP
TOUCHBAR VS FUNCTION KEYS
Let's cut to the chase here. Compared to the old keys the TouchBar is capable of about a zillion ADDITIONAL things and will only expand in functionality over time. If you want to use it in the most basic ways, it's about the same. But you can't deny that it's just a far more versatile way to use that space. Winner: tMBP
LEICA vs NIKON vs CANON vs tMBP
As someone who earns money from shooting (going back to using 8X10 large format and doing all of my own processing), let me say this: Few WORKING pros shoot Leica. They are beautifully made but lack the speed and top tier sensors required for most pro shooters. Compared to the resolution and dynamic range of a Nikon D810 or Canon 5Ds, the Leica is little more than a slow moving toy. Yeah, I own one, but it sees little use. If I want a old-style shooting experience I'll grab the Nikon DF, which also outperforms the Leica. I can't see comparing my tMBP, which is a highly capable and versatile machine, to a highly restrictive Leica. If you're talking about build quality, then yes, a tMBP might be the closest thing, but that's about it. Winner: The guy who didn't blow 8K on a Leica!
Folks, we have tons of cool options for laptops and cameras these days! Everyone should smile! Happy holidays!
