Maybe it's just me being greedy, but the education discount is always so small. But it's better than nothing.
Maybe to you, to others it may be a power platform. Whatever floats your boat. Besides, just because it doesn't sell as many units doesn't mean it isn't important. There aren't very many people who make movies, but a lot of people watch the movie maker's products. However, I would like to see something more like the Cheesegrater Mac Pro and various Power Macs where you could actually add/replace multiple drives, PCIe cards, etc.
It is simply impractical to make something in the form-factor of the iMac AND have decent upgradability. If you want that, then wait for the Modular Mac Pro.
Besides, people have been routinely spending 5 times and more than a maxed-out iMac Pro for basic transportation, when all it does is get you from one place to another without getting wet in the rain, and THEY don't whine about not being able to "upgrade" their engine, transmission, seats, headlights, etc. after the sale. In fact, of ALL the "technological" things we buy in our modern lives, DVD/BD players, AV Receivers, Microwave Ovens, Smartphones, Lawn Tractors, Televisions, Tablets, Synthesizers, Oxygen Concentrators, et cetera, WHY is it that the ONLY, the ONLY, thing we get ALL upset about being "upgrade-able" is our home Computers, no matter how small, or inexpensive, or tightly-integrated they are?
It's just a throwback to the way computers were first offered for sale, growing out of a hobbyist and DIY market, that has conditioned us to "require" "upgradability".
Well guess what? Those days are coming to an end, and consumers, which a vanishingly small percentage of, actually DO "upgrade" their computers, have only themselves to thank/blame.
I would make a large wager that, in reality, 95% of the world's "upgrade-able" computers go into the dumpster with 100% of their OEM parts inside. And that it has been that way for the past 15-20 years.
