I'd say its importance depends on what kind of phone you carry. <g> FWIW, "BlackBerry 10 is based on QNX, a Unix-like operating system that was originally developed by QNX Software Systems until the company was acquired by BlackBerry in April 2010." from https://en.wikipedia.org/wiki/BlackBerry_10 > For Android, the answer is mixed.

Nice, with PHP it isn't so easy; not only is there often no PHP interpreter, to install one you have to fiddle with a config file. > Somewhat intermediate between stand-alone exe applications and a > directory full of scripts is to create a package, compress it into a > zip file, and run that zip file with the Python interpreter installed > on your system.
