Tried the ribbon several times, still hate it. Maybe good for novices, or to learn the shortcuts, but it's miserable for me. To each their own I guess.
Spreadsheet embedded in a word doc is possible in Office 2Kx, OOo, and probably others. It's clunky in every case I've tried, maybe not so in RagTime? But if it really is just OLE, then RagTime isn't as cool as I thought, or at least is not what I was envisioning above, with a single app of multi-capability and "modes" for each task.
