Hi,

my answer is this: i use my n900 for running some of my python apps that are useful for me (mostly database apps such as tracking my water and electricity meters etc); run kali moto in chroot and use the camera to take raw images and then edit them in lightroom (i like the way the camera takes pictures). That is all... sadly... Sometimes i use it download and convert files but since i have a rooted phone with Termux; PyDroid3 and Tasker it is far enough for me at the moment...
