I've been thinking of getting my mom an old iMac G3 for her antique shop. The employees would only need a computer for browsing the web, and maybe emailing, so a G3 would be fine. I was looking at some cheap G3's on eBay, and many were loaded with 10.4, but with only around 128 MB RAM. It seems to me that Tiger running on a G3 would be insanely slow. Is that true? Not that the shop needs a supercomputer, but I'd like it to be somewhat decent. Would OS 8/9 be a better choice?
