During last days I moved from my C760 to Tosa. It is heavy, big and has awesome screen — I can use it even with lowest brightness setting (one step from “no backlight”). Stylus is made from plastic but is longer then styli from other Zaurus models. Internal WiFi is able to do WPA on firmware level but driver do not support it ;(
First day was SharpROM day because I forgot to take CF card from home to flash OpenZaurus. SharpROM looks quite OK but some things was weird. For example handling of QVGA applications — screen was switched into 240x320 mode with ‘please wait’ message on start and exit… This slowdown plus no possibility to switch off that switching force user to rather skip using such apps. WiFi settings has profiles support which is nice but due to fact that internal wireless use wlan-ng drivers I could not get WPA so was not able to connect to my home AP.
Same day evening I flashed OpenZaurus 3.5.4 (OPIE flavour) into device. System boots and works but I needed to install some upgrades to get fixed keyboard mapping etc. Reconfigured AP to get connection, configured WiFi in tosa and ipkg update;ipkg upgrade was working. Lot of stuff upgraded and after reboot I got working keyboard but lost HostAP configuration files (will hunt this bug and add proper fixes into OpenZaurus upgrades feed). Lack of Control key make it not so usable with OPIE terminals so I use OPIE-IRC on it instead of logging into my irssi-over-screen session. And there are two keys which functionality is something which I must find out (one above Cancel and Backlight/Rotate one).
Machine works quite nice but after using 2.6 kernel on PDA for over one year I feel that 2.4-crapix is slow… Resuming from suspend need time to get machine responding, enabling WiFi means machine not responding for a while too… I hope that 2.6 will get into usable state soon.
