I know how to drop a bunch of files on an SD card, and I know how to to write C programs in a UNIX/Linux environment, but I don't happen to know the ins and outs of ARM assembly (I've done lots of assembly, but only on CPUs designed before 1980). I happen to be going through the Cambridge tutorials as a quick way to pick up the things that are new to me because of ARM, and to pick up what specific directive syntax GCC's assembler wants (my first program failed to compile because it didn't like my attempt to put to-the-end-of-the-line comments after a semicolon). I already teach folks at the hackerspace how to build projects with Arduino. For all the thousands of R-Pi units that have already sold and how many more will be sold, it's going to be a part of the hobby ecosystem for some time. I am looking at what's out there now because when the supply chain problems are finally worked out, I know there will be a clamor for courses to teach a whole new round of folks what it is and what they can do with it. Is it perfect? No. Is it $35? Yes. It's going to be popular, especially with people who just see the initial price tag and want to do *something* with it. -ethan
