I use the Tinkerboard S and I absolutely love it. It’s so much faster and the dedicated EMMC storage helps a lot. Try it. The ecosystem is much better than it used to be.
I essentially have. If you compare the specs of the S vs non-S you'll see they basically didn't change anything. Same CPU, GPU, memory, clockspeed etc.
It's not terrible but I had somewhat naively assumed it would be a rasp-like experience but more powerful.
