Today I did a significant update to "We have iMac at home." Today at Chicken Alley I picked up a used Apple Thunderbolt display for $60. It was pretty grimy and the power cord (which is permanently attached, because AAPL) showed signs of being yanked on. Of course, the display didn't work at all, but it served to remind me that I already had one. It's a slightly different model, I got it for $25(!) and it happens to work fully. I spent an hour removing the monitor, speakers, webcam and USB hub (the Thunderbolt Display serves all of these functions) and got it working with the 2012 Mini.
They work together seamlessly. That Macally mini keyboard is awful. Mum figured out something like 1/3 of the keys don't work properly with shift. That's not a "bad keys" issue, it's "something is wrong with the chipset" one. I've been shopping for decent third party Mac keyboards that are small sized and not crap. The market is terrible. I don't want crazy clicky Red switches. I don't want to pay over $300 (Seriously, look at the price of an HHK these days.) Keychron makes a lot of great models, and they are Al.. Out. Of. Stock. Unless I want a $275 Bluetooth one.
