I feel that is why the wheels are priced at the level they are. It’s an optional accessory, and a low-volume and niche one at that, and the price reflects this.
Nonsense. The Mac Pro may account for less than 1% of Apple's Mac sales, but that's out of
20 million so they're still being mass produced by the tens of thousands. If we were talking about, say, custom Apple Silicon processors, which cost a fortune in development and tooling up costs, those numbers might be a problem - but a furniture castor is a furniture castor. You can get them for a couple of bucks
- or you can get a set of nice-looking ones that wouldn't be out of place under a Mac for £20, made to plug in to a range of ~£200 filing cabinets in place of feet (just like the Mac Pro & probably selling in similar numbers).
If some quirk of the Mac Pro design means that the wheels have to be hand-made in tiny batches at vast expense
when they're just wheels (and don't even have fancy features like brakes) and could easily be sourced as a standard part then that is just plain
bad design (good design
doesn't ignore practicalities such as cost)
. Likewise, "economies of scale" are no excuse for the Studio Display height-adjustable stand when most other high-end displays
with far smaller potential markets than the Studio Display have them included.
However, I suspect that the mark-up on those wheels and stands is something like 1000%, and they rely on customers price sense being temporarily numbed by having just laid out $20,000 for a computer. Also, it's probably helpful when negotiating large commercial tenders: sweeten the deal by throwing in a bunch of "$1000" stands and "$400" wheels for free.
The problem is that Apple are going for a "Luxury Car" style pricing policy of raking in profit by adding on over-priced extras after the punter has decided to buy the car. Looks like it is doing OK (for Apple) in the short term - although its unclear whether that's because there's a market for the computer equivalent of a Bentley or just because users are so committed to the platform that it is cheaper for them to pay up than re-tool with a cheaper PC system. The problem in the latter situation is that it locks Apple into a pool of established users that is only going to shrink with time. Certainly in the pro area they're not even trying to win customers from "the other side" and while constant whinging about the Mac Pro wheels and display stands may seem petty, I know from talking to my (pro) PC-using friends that the publicity around those prices has
really cemented their idea of Apple as source of laughably over-priced bling.
