# Notes about some hardware aspects 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 -kh Filesystem 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.
