Thanks for the replies. I must say however that I'm as much in the dark as I was before I asked. I know now there is a browser out there called Netfront, but I've no idea how to get it. The Access web-site (makers of Netfront, apparently) have no download for the Zaurus. Will one for ARM work? Will it work with the original ROM? I searched this site's download, software index, and feed links, and didn't find Netfront there. The so-called beginner's (getting started) FAQs are off-topic on the basics, so I'm in the dark as to how and what software to install.
Following the Amazon fiasco, I bought a PocketPC for my brother, and he's happily surfing doing all sorts of things, whereas I'm stuck with my Zaurus with no clue. And I'm sorry to say this site is unhelpful from a newbie perspective. I envisioned wirting a real "Getting Started FAQ" explaining the big picture down to the tools, but I just can find enough information to use my Z myself to begin with.
I look back on my experiences successively as system administrator, developer, and business user of Debian, and I know it's not me. And it's not a fault of this site, because it is free of charge, and volunteer.
But it is obvious why Sharp doesn't want to sell to non-business users.
