Everything else is rubbish? Sorry thats ********. While I conceded Dell make some cheap crap, they also make quality professional Laptops. You get what you pay for.No one has thunderbolt 3/USB-C yet so I have to assume it's not available yet, the USB C in the macbook is only 5Gb/sec transfer speeds not the 40Gb/sec you are talking about.
Wrong, Dell XPS 15 and 13 and Precision Workstations shipping now with USB-C / 3.1 with Thunderbolt 3.
As for the graphics cards, they are what they are, mid to high range AMD mobile graphics cards, they won't be brilliant for gaming (although certainly very capable) but should be fantastic in FXCP and similar so no different from any other iMac ever made. Personal preference, but most peoples preference and mine would be for the familiar Nvidia 960m, as per almost every other comparable laptop. AMD barely used anywhere, and info on specs equally scarce, from even Apple or AMD to make an informed choice.
As for your wants you are clearly in a niche market and they have stopped making niche products.
Although the mini was down to intel not having the same socket on the quadcores as the dual cores that is the only reason the quads went in the 2011/2012 machines because they could do it without retooling and developing a separate motherboard. If they can make Quad core laptops they can make a Quad core Mac Mini - a look on these forums alone shows just how much in demand a quad mac mini would be, and in fact just how much 3 year old used models can go for...more than new.
The macbook is your retina macbook air and is a better product on release than the air was on it's release by an order of magnitude, it is also the most powerful core M fanless laptop you can buy so it seems they are getting the most out of this new technology, certainly not losing that race. This probably true, but slightly too weak currently for my needs. Architecture design software Autodesk and Refit and MS office.
The 15 inch rMBP is not a gaming laptop it's not marketed as one and it is specced out perfectly for long battery life for using professional video editing apps etc in the field which is what it's designed for. Maybe not what you want but again, so what, they don't make products for you they make them for who they think will buy them most (a good business strategy that). Well I didn't say I wanted a gaming laptop, in fact I specifically mentioned video editing, but I also use professional design software applications in the field on various client sites internationally. I am exactly the target market for fast hard drive, long battery life, well built, enjoyable to use, professional system. Money no object as I earn my living from it.
I don't game.
I know its not a gaming system, but it does come with a low/mid gaming card, as opposed to a professional graphics Quadro or Firepro version, assuming it even comes with a graphics card at all.
By all means if apple don't make what you want buy something else I can't see any need to whinge about it, oh yes it's because you know that whatever else you buy will be rubbish and you'll wish you hadn't touched it with a barge pole, specs never make a product you should know that by now....
Dell Precision Workstation laptops are expensive professional machines, in a way that Apple can only dream, i.e. they use professional graphics cards, can last all day when running Cad or demanding software at full pelt without overheating - MacBook Pros despite their name do not.
The same Dell Precision Workstn range have a 3yr same-day repair/swap policy (better than Apple care at similar extra cost option), and with a far superior build quality in terms of surviving a fall or impact.
I want to buy Apple for the same reason as everyone else, i.e. I am conceited, I like the looks, it has cachet, etc. I am just disappointed that Apple is not leading by the margin it used to in some ways.
And this is the perfect website to whinge about it.
