Recently the Samsung Gear 2 and the Samsung Galaxy Gear (Tizen version) have got rooted. Now this opens up more possibilities, and for the seriously tech experts you can do funky things like installing busy box on your Smartwatch.
sdb root oncommand
rpm -i busybox-1.17.1-2.3.armv7l.rpm
Now you get a VI (a CLI text editor) on the Smartwatch, one use case is that you can now edit xml and config files directly on your Smartwatch.
Let us know your thoughts in the comment and happy busy boxing !!!!
