Yes, the Zaurus section of the forum unfortunately has a very low activity since many years, which is expected since only the SL-5500 and SL-6000 models were sold outside Japan. I still have my collection of Zauruses and switch them on from time to time, I read the posts here with interest.
I suspect there are other users following the various threads but they never answer. We have a views counter for each thread, there are between 5000 and 19000 views for each of them, though most of them are be probably made by bots. I prefer to keep the subforums open for read-only access for non-registered users, so that it's easier for Google to index the pages and make the information here more accessible.
Other users that have posted here in the past are probably following this subforum. To any of you, please post here so that we can have a rough idea of how many of us are here.
