I'd have to say that the walker is the least popular. The case design just didn't make good sense, not to mention that the white disk drives against the black case clashed. As for the A600 well, when Walden Software was selling them on the cheap I bought as many as I could and sold them to friends who loved them due to easy TV connectivity, easy portability do to it's compact design and the fun factor of course. I had one friend who expanded his with an accelerator, ram, and 3.1 roms, got online and used it to do some web design. I also read about a guy who used one to run a desktop publishing company and the only expansion he bought for it was a ram card. So the A600 was really the first minimig and a pretty nice machine in my opinion.
