"Gadgets running Linux are a lot of fun, but much of the value
of using Linux is lost if the resulting device is locked down and
not hackable. In cases where the device has been opened up, no end
of creative hacks have resulted; see, for example, the OpenWrt
project. It is hard, however, to imagine a device with more fun
hacking potential than the Linux-running Motorola a780 cellular
telephone. There is no end of interesting things which could be
done (and annoyances which could be fixed) if that platform were to
be opened up.
"The good news is that Harald Welte has managed to open the a780
and install new software onto it..."
