The touchscreen is capacitive (my old Openmoko Freerunner's is resistive). This makes it difficult to use some pen or to address a given pixel in apps.
The hardware (i.e. it is not an software issue) has no support for external monitors like MHL, slimport, HDMI, etc. The same seems to be true as well for the newer BQ Aquaris E5 and for the Meizu MX4.
The available disk space is like this:
$ df -khFilesystem Size Used Avail Use% Mounted on/dev/mmcblk0p6 2.0G 1.6G 369M 81% //dev/mmcblk0p7 4.4G 273M 4.0G 7% /home
Write permission is only below /home, the rest is mounted readonly.
