I guess I’m easy to please, but, recently I got myself a better bluetooth dongle over the holidays. I had one before, but it was stupid cheap, connection was frail and didn’t have good range. Now I have one with Bluetooth 5.4 and I’m amazed with what I can do with it.
I can funnel sound to any one of my bluetooth speakers so I don’t have it hogging my main speakers when I want something close by me.
Speaking of which, I wish I had really known this far earlier in my days of using a computer. But, being able to split audio in multiple ways. I can assign where sound is going to, program to program. One browser gets these headsets, that browser gets the TV speakers .etc
That kind of shit amazes me and damn shame I never explored this before.
The pencil. Seriously, what piece of tech has had such an impact as this ~450 years old lump of graphite sandwiched between two pieces of wood? (edit: grossly simplifying it’s evolution, I know)
So impressively efficient it is still widely used today and, imho, in many cases still unrivaled too. Heck, even Apple with all its billions could only try to copy the cheap & humble pencil with their expensive high-tech ‘Apple Pencil’—they did not manage to put an eraser on their model, though ;)
