Reasonable point, although something working out which mode is 'right' is not so easy (I'm still not totally sure of units!). Certainly it's possible to avoid math mode for many things by doing a bit more macro programming (e.g. you can vertically centre without \vcenter with a bit of measurement). -- Joseph Wright
