Many years ago, I measured performance per watt of the original Raspberry Pi when they were still relatively new. The performance per watt lagged behind even a beefy Intel box since the original Raspi was so slow that it destroyed any gain it got from using so little power.

EDIT: One set of benchmarks I found as an example: https://bret.dk/raspberry-pi-5-review/#Performance-Per-Watt

As an aside - as someone who used ME back in the day, I feel like I honestly had more problems with Vista. ME was a downgrade from 98SE for sure, but I don't remember it being the same level of performance and reliability degradation that I saw going from XP to Vista pre-SP2.

I otherwise agree that the older Win 2k era UI was pretty much an ideal UI. The whole "frutiger aero" look did not age well.

On later generations of IBM terminal keyboard, you'll see | on the shift-1 position, and a separate key with the broken-bar (¦) symbol. For example, on this keyboard, the broken bar is below the backspace key along with the \ character. https://sharktastica.co.uk/image?id=qhTU8QvD

The reason for the two different types of bar/pipe characters, and why the original IBM PC keyboards only had the broken bar on the keyboard, involves a particularly arcane footnote of history relating to supporting the PL/I language on ASCII terminals: https://www.os2museum.com/wp/a-wunderbar-story/

As an aside, it's worth noting that moving between fields was important enough on IBM terminals that they had a dedicated "back tab" key located on the opposite end of the keyboard to the tab key. On the original IBM PC, they decided to combine both functions into a single key. As a result, the tab key on the classic PC keyboard features the symbols for both forwards tab and back tab on the same key, the back tab symbol being on top to indicate that you need to hold down shift to use that function.

EDIT: The 5250 series terminals used the terms "Field Advance" and "Field Backspace" instead of Tab and Back Tab, but otherwise they used the same symbol on the keys, and the keys were located in roughly the same position as the 3270 series.

As someone who mostly understands what's going on - It does not seem like wizardry to me, but I am very impressed that the author figured out the long list of arcane details needed to make it work.

An interesting detail, given the ongoing rumours that the next major version of Windows will require an NPU with a certain amount of performance.
