Currently the HELIO is only available with a proprietary operating system. See FMS(http://www.fms-computer.com) for information about the Linux port.

Got started with PicoGUI (the GUI API of PicoLinux) to make some PIM apps, deciding on a file storage mechanism was vital, after some days work right now my Helio looks like:
Currently: * Unofficial VTech Linux ROM includes: kernel 2.4.0 test-3 (4bpp, unix-sockets ) no TCP/IP so can not try pppd microwindows (terminal, virtual qwerty keyboard, clock, useless demo appilcations) busybox (for all the posix commands ls, init, cut, etc.) libc, libm, and a few other necessary libs rz / sz (zmodem for serial transfers) gzip / gunzip / date and assorted stuff
Features: the RAM drive has it contents through power cycles and battery changes 16 levels of grayshades
* 2 MB RAM drive libs: pgui / jpeg / gdbm / sqlite
PicoGUI: pgserver (like X server) / virtual keyboard (qwerty/fitaly) / terminal (configurable font size) image viewer (jpeg / pnm) / vrcalc (agenda vr3's port) / games (blackout / battleship) / launchbar / uspread (my own buggy spreadsheet)
Hacks: (to get PIM functionality without effort on gui) commnand-line tools tdl project from freshmeat: todo list manager scripts for expense management script for mileage
Others: sqlite (hacked to get dynamic linking) is a light weight DB on top of gdbm. the command interpreter though need too many libs so grabbed the statically linked binary for agenda vr3 (same processor family) its working. STILL have 650 kB free :)
The Future: * design DB schema * coding PIMs using pgui and sqlite
