In case any one missed it, /u/the_bo posted a viable solution on to "how to install a web browser with OSMC". I haven't tested it, but it seems legit.
I will also point out that there are very easy mechanical ways to solve the "How to Install a browser in / on OSMC" problem. I'm on a Raspberry Pi 3. You can just swap out the OSMC micro SD card to a Raspbian card and reboot when you need a browser. I know... this is an extremely inelegant solution, but it does bring me back to the days of cartridge consoles. This is not my solution.
Another solution, if you feel like geeking out, which I do not at the moment, is as follows. Feel free:
My solution for now... somewhat inelegant but close enough for me... is... to buy a second RaspberryPi and keep OSMC on one and Raspbian on another with a remote control HDMI switch.
So now I have 2 RaspberryPi's, 2 Bluetooth Keyboard/Track-Pads (need two sets for the two dongles, one for each PI. Only one Keyboard/Track-Pad is needed to operate the two RaspberryPi system), and an HDMI switch remote control. Good enough for me. An added bonus to the remote control HDMI switch is that DVD players and other media sources can be easily connected to the screen. To be environmentally conscious, the whole thing - RaspberryPis, DVD players, HDMI Switch and so forth, can be kept on a power switch to avoid draining electricity.
Eventually, I suppose I will migrate the whole thing to an Android phone - please let us know the best way to do this if you do the same.
To all the people complaining about "still nothing?" and what not, you do realize that the author of this software didn't have any obligation to make it available open-source for free, right? I mean, the author could have written it and used it for the author's own use, and maybe some close friends, and you would have never known it even existed. So... if there is anyone that wants a browser in OSMC and wants to talk cash, just post your cash number here and we can all laugh at how few digits you had in mind.
