My problem with most thin clients is that they are artificially limited in the memory department. Even a machine with a single SODIMM slot can be expanded far more than most of them allow. I get that's not their point and they fear that they will cannibalize sales and so on, but that still leaves them irritating to me. I don't like to have swap space, I find it offensive. Having lived through the time when the memory was the expensive part of the computer, I would rather live in the now, where I can have 64GB. Or in something small, at least 8 GB. Any less than that, and I'd better be using it as a microcontroller, and it ought to have an even smaller power budget than a thin client.
I know, I'm spoiled. Frankly it happened to me early, when I bought a used Sun 4/260 with 24MB RAM at a time when most people's PCs still had 4 or maybe 8MB from a dude who had the loft above a sporting goods shop in Soquel, and had it stuffed with weird old machines he was selling. Don't want to pay for the power for a big bastard like that now... and those square feet of DIP-packaged DRAM.
