Just a shot note today. I use the Cyanogenmod (~Android 4.4, I guess)
not the WebOS, unfortunately. But the TouchPad is more useful with the
Android these days.
So here is the list:
* Overbite Gopher client
* Lightning WWW browser (when gopher is not enough)
* Addi Octave port (it seems to be abandoned but it works)
* SGit (Git client)
* TotalCommander (for ftp and file management)
* SmallBASIC
* AndroWish (for Tcl/Tk)
* VimTouch (to edit Octave and BASIC files)
* Markor (it has nice support for todo.txt)
* Terminal (for SSH)
I use the FDroid to manage applications. Most of normal programs are
marked as non-compatible with my OS/device so choice is limited. At
least I have found a more current Terminal Emulator program here (with
more up to date SSH).
Anyway I use the device mostly for off-line work (Octave programming
etc) and my main way to consume online stuff it the Gopher.
I have the Bluetooth keyboard and the mouse for the device so even the
terminal and Vim can be used in almost desktop manner. So I can do
simpler thing here and it is not necessary to turn of the Blackbird
desktop or the SGI workstation.
