I genuinely believe that up until Apple's mea culpa last year they had intended to ditch the Mac Mini, Pro and MacBook Air. The naming conventions make sense and I think the lineup was going to look like this:
iOS:
iPad / iPad Pro (Mini dead/discontinued)
macOS:
Macbook / Macbook Pro (Air discontinued)
Mac / Mac Pro (current iMac & iMac Pro; Mini and headless MP discontinued)
The 'iMac' naming no longer fits with macOS but their hand has been forced. I think the iMac was going to be rebranded as purely 'Mac' with the new iMac Pro becoming the only 'Pro' model. That machine is way too fully formed (look at the cooling system!) to have been knocked up in a panic - it was always going to be the 'new Mac Pro' IMO. It also fits the mentality of reusing the parts bin (stand/casing/screen/keyboard/mouse) with a lick of paint to keep existing tooling for higher-priced SKUs.
Of course, the backlash to the MacBook Pro (butterfly keyboard/16gb RAM limit/Touch Bar) wrecked those plans; pros had finally had enough, especially with no other new 'pro' hardware on offer. I don't doubt this completely changed Apple's positions (there is still zero indication from the supply chain or otherwise of any new Mac Pro or Mini designs) and they really are starting from scratch now.
They are also in a tight spot with the notebooks - the 2015 Pro is still for sale and they can't ditch it or the Air as (1) they sell too well and (2) the regular MacBook shares the same issues (port restrictions/keyboard) as the new Pro.
What a mess.
You're advocating the removing of the i then
The naming convention is fine but they have to keep "iPhone" because it's just an all-pervasive brand now. They could have called the iPhone X the ApplePhone for example but you can see why it's so much easier to stick with iPhone.
In a different way, they originally wanted the AppleTV to be iTV before the
British broadcaster complained.
The touch bar and touch ID assembly adds a lot of to the price of 2017 MacBook Pros but there's just too many examples of 2016 and 2017 models going on sale at third party retailers at huge discounts for it to be a coincidence - are Apple tacitly allowing select retailers to sell cheaper versions of hardware?
Is it like going to a designer outlet shop and picking up an out of season Armani jumper for a fraction of the cost of brand new stock?
The old 2012 non-retina MacBook Pro stuck around for four years until the launch of the 2016 model saw Apple offer a basic version of the otherwise discontinued 2015 series as a cheap option alongside the 2016 model which saw price increases in part due to currency changes (in the UK at least).
The MacBook Air has not had a substantial upgrade since early 2015 and that was just a minor speed bump over 2014 models so we can say that it's there to fill a price point and draw people to the more profitable models.
Both of these mobile models are there for people who can't afford the higher priced 'Pro' models and also to make them look better value for money for the people who can afford them. Is it any surprise then that they may well sell incredibly well despite looking the poor cousins of their more illustrious modern upgraded models?
According to Apple we're getting a headless modular Mac Pro and logically you'd expect a lower spec consumer 'Mac' below that to make the higher end model look more attractive. Current specs could be priced up to a $2000 without keyboard and mouse but at best you get something that only has 2 cores and pretty ancient graphics.
I think as long as Apple give the Mini a proper refresh most people will give it serious consideration whatever specs it comes with and I suspect a price increase at the base level is coming as the Mini is the only Mac with 4Gb entry level specs - 8Gb is surely the minimum over three years after the 2014 model was launched. If that is the case then I'm hoping that Apple lift the price range of the Mini and the spec accordingly. Anyone who needs value computing should look towards the iPad.
This is even more the case if the modular Mac Pro starts well above $3k - the iMac Pro is priced at $5k because of the high base level specs in a machine which isn't easily upgradable.
Why couldn't a modular Mac come with higher specs as standard but still allow access to RAM slots and drive bays so users can fit their own in case of damage? Surely such a modular Mac Pro could come with AppleCarePlus to include accidental damage in case of user upgrade disaster?
