similarly, will accelerometers always be used as input devices ?
of course not, they have been used e.g. to spin down hard disks
on laptops when they are shaken too hard. Still they have quite a
fair bit of usage as input devices; you've seen it yourself,
right ?

in the end of the day, when you put those on mobile devices
like e.g. cellphones, app developers will be really keen on
creating new ways for interacting with apps (be it a game
or not) using those devices, so I will agree with Jonathan
that, maybe, having two separate drivers for different
purposes would make sense, although that might cause a bit
of trouble if user ends up enabling the wrong driver when
building custom kernel for his device.

My hope is that we can make use of a well known and uniform
API for all input devices in a device, be it a keypad,
touchscreen, accelerometer, magnetometer, gyro, or whatever.
