Depends. If vthe 3200/3500 has any sort of RF communication ON THE BOARD, then it's worth it for most people.
yasee, I found Albert's website, and his Mod would replace the Hard disk in a 3100/3000 (hence why there's no point in using a 3100 for Alberts mod, unless you like black)
Although you all already knew that. XD
So, the advantage of a new zaurus with onboard connectivity (Even just one of Wifi OR bluetooth) is that it free's up expansion. Either the internal CF Microdrive slot, with an AlbertR hack, or a CF slot in normal use.
heh, if the Linux BlueTooth implementations were as good as the Windows drivers, then Sharp would make a MINT in the US/UK on the zaurus with inbuilt RF.
Unfortunately, unless Sharp want to seriously spend revenue on an open-source project, or the BlueZ or Affix drivers suddenly become as fullfunctional and easy to use as. . for example, the SCSI, IDE and Network drivers in the kernel, We're boned on that. Might one day get wifi if we're lucky!
