Dude you're on the cutting edge. I don't think HiMD has been
released in the UK yet. I'm interested in one but I don't think I can afford it - I like the fact they can now record at full CD quality uncompressed. As for working with Amigas I didn't know you can get USB for Amiga - but if they work as a 1Gb storage device that would be "cool"!
