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.
Why should it not need a high-end server? How else are you willing to secure the network if not with high-end servers?
If you can run it on a smartphone, then the network is as weak as a smartphone (which are purposefully less powerful than desktops and laptops). I wouldn't trust my life savings to a smartphone-powered network.
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.
Microsoft Office and Open Office are different products with different goals. You shouldn't think they are the same.
Also, as easy to use as possible will never be equal to usable by everyone. You can't please everyone, and any developer knows (or should know) that.
