Unfortunately, layer after layer of framework on abstraction on framework on abstraction sometimes means that we need a supercomputer to render a user interface, and still end up with perceptible lag. :)
Regarding elsewhere where I mentioned running BOINC on a Pi 4B, I'd also note that (at least from a RAC standpoint) it's almost up there with a ThinkPad X201 Tablet with an i7-640LM throttled to 1.2 GHz. If I switch the BIOS from "balanced" to "performance" mode, the ThinkPad will run a bit faster but within an inch of thermal shutdown. I might be able to overclock the Pi enough to achieve parity with the throttled i7.
Eight years ago, I'd never had guessed that we'd see the Pi turn the corner to become a usable general-purpose desktop.
Every Pi SD card has ended in irreparable disk corruption. The SD hardware’s wear-leveling and delayed allocation is fundamentally incompatible with any device without a battery, especially with frequent writes.
The “official” solution for the Pi is to use read-only SD cards with overlayfs. That’s not the default and it’s not how entry-level users will use this.
Also, don't under estimate the performance of future SD cards.
v0, get it shipped
v1, improve

I know there are other power down issues with SD cards and corruption well. I think in a class setting I would have important files replicated to an NFS server, with at least hourly snapshots.
My primary laptop is a newer T25 because I couldn't resist the keyboard, but my primary desktop is still a 9-year old AMD FX8350; with 32GB of RAM and SATA SSD, I game, Lightroom, Photoshop, VMWare Workstation, and anything else I need easily enough.
+1 for i3. Been using my Thinkpad W510 with i3 non-stop since 2010 and it's still working like a charm. For the past months, though, I've had to use a Dell XPS 13 for work. Now that I've equipped it with i3, as well, it's merely using 3.5W while I'm doing ordinary computer work and some coding, meaning that I can get 15 hours of battery life easily, and often even 20h. Absolutely mind-blowing.
I think broad computer illiteracy in the general population has convinced people that you "need" a new, powerful computer. In reality, 95% of the population can get away with any decent computer from the last 10 years. Grandma isn't training a neural net, she's checking Facebook.
I continue to use a 2nd generation i3 desktop as a "daily driver" for a lot of my computing/server needs, without issue.
