My SAM is more than powerful enough. The problem is and always will be software to run on said systems.
They aren't too terribly friendly to legacy amiga progs without emulation. There's no real modern browser, etc. I could no more use the X1000 as a daily driver PC than I can my SAM. Can't even navigate modern websites with the thing, for the most part. I love it for what it is, a niche "fun" machine. I run an old school BBS on mine, and it does that admirably and completely silently (Patriot SSD, silent PSU).
Could be 5000ghz, 24 cores, 100 GB of RAM and sing and dance - but the software just isn't there for OS 4, lol.
Buzzfuzz: you are very correct that many people, even myself on occasion - find said systems to just be dust collectors. It's hard to justify expense vs. function, even for the much lower priced SAM's.
