What you'll find is that after a while the locked down filesystem which
usually requires a proprietary windows only application to make updates or
complex contortion to interact with in Linux is a real pita. Don't even
think about using external hardware that requires a custom driver to be
installed.

When forced to work with Android devices I prefer to use adb to interact
with them.

./adb shell

You can also use adb wirelessly if your device supports the wireless flag
which is pretty handy.

setprop service.adb.tcp.port 5555 & stop adbd & start adbd

Depending on your distro you can get access to adb as a package or if that
is not possible for you might have to install it via the android sdk.

Then you can use your desktop to work at the system level while still
retaining access to the touch interface for other things...
