now we're cooking with gas...

Now I work across two computers - ScrumpyToo, my MacBook Pro, when I'm at home, and Ace, my wee netbook, when I'm out and about, I could really do with a place to keep some of my writing which I regularly use on both. Right now I can't find my USB stick, and anyway, it'd be REALLY handy to have somewhere online I could store it all, work on it, and have it updated on both my machines. Sorta exactly like GoogleDocs does...EXCEPT GoogleDocs won't accept some of my longer works as it runs over their size limits! PFFFFFFT.

So whilst I could split it, that would be sorta annoying...so does anyone have any other suggestions? Got to be easy to use, compatible with Mac and Linux, and most of all FREEE.
