So was it the technology that forced Apple to keep the slots? Was it competition that forced him to put them in initially?
SJ was forced out of Apple a couple years before the Mac II (1987). A major issue was that the original Mac had underwhelming sales and he resisted "fixing" it (i.e. making it more expandable like the Apple II and traditional PC's of the time). SJ had no interest in the Apple II even though it was Apple's bread and butter. He always saw the ultimate goal of the computer as an "appliance".
You have to go back to the beginning of the 1970's "PC"... most of those "kits" were dependent on slots for adding basic functionality... that just naturally evolved with the Apple II and a few years later with the IBM PC (and clones to follow). If you needed a serial or parallel port, you added a card. If you did mostly office productivity, you got a hi-res monochrome card... if you needed color, you got the best color card you could afford. A little later, if you wanted more than beeps, you needed an audio card. Over time, as those features were integrated into the basic computer, there was less and less need for expansion slots. Their usage became less and less... now it's mostly people updating old computer on the cheap. Again, not saying that's a bad thing, just that it's
understandable that Apple doesn't really care about the second-hand Mac market since they don't get paid again after first sale.
Yet they seemed to be proud of what the compute could do and promoted it as competition for the PC. I guess I didn't understand Apple a lot longer than I thought
Apple has always looked at the angle of how they
distinguish themselves from the competition. They aren't going to win on price. It's really all the same hardware on the inside. They have to make the case why they offer a solution that is better than then the competition. That doesn't mean they necessarily got it right or failed.
Then none of the workstation class machines from entry level through the Z800 type were of interest to Apple.
There's a focus here to focus on the "tools", i.e. "workstation" vs something else. Apple is always focused on the "solution". What is it that you want to accomplish? Here's "X" solution for you. You may not like the form factor or the cost, but they do offer solutions that cover about 90% of the consumer market. As they see it, it's not in their business interest to focus on that last 10% - they believe it will compromise the 90% they do focus on. Again, I can make the argument it would be in their best interest to get that up to 95%, but that's not how Apple sees it, and that's the point.
So then, what do you think is Apple's market? Is the MacPro an indicator of the future of the desktop or is it just an example of one segment of the desktop?
For as much longer as the "desktop" exists, yes, most of the desktop market is moving towards closed appliance-like computers. Even usages like render farms will move more towards low-powered appliance like boxes that you just "plug" into (whether literally or figuratively).
Thanks for contributing to the discussion. I guess I had an idealistic impression of Apple, it's focus on professionals and it's direction.
I've been a general computer hobbyist for well over 30 years now - I've lived and read the history, follow the industry, and like to talk shop. I'm generally a fan of Apple products, but hate Apple fanboism. I do "get it". I get as frustrated with Apple as anyone here. But I also deal in reality.
