OK, I use the wrong words. You SHOULDN'T run a full node in a cellphone. Its battery will run out quickly and your bill will be enormous for the data use. If you'll leave your cellphone connected in a spot, never to be moved, then just install a computer there. Don't do such ridiculousness.
The point is that you do not need, and should not need, a dedicated high-end server.
If you can run it on a smartphone, even if you shouldn't, indicates you can easily run it on any desktop PC.
I agree. Word isn't designed to be used by everyone. Its price is also something most people can't afford.
This point works equally well with Open Office. And an office suite *is* designed to be as easy to use as possible.
