Even if KSD or now FireMonkey supports ARM Linux this does not mean
anything for Android. While Android does support native Linux
applications it does not have a X server. Currently the only possibility
for this is to run a X server through a VNC viewer and thus you can not
reproduce the usual
And more important for me: the same code I can use on several OS:
Android, WebOs, Linux, Windows, .. iOs ( I hope that FPC will be able to
crosscompile to iOs soon), server can be embedded or standalone
This might not be possible from non Apple targets, because of Apple's
licence restrictions
