Much appreciate the nits! I've made a few minor tweaks right now, we will do a more complete revision later on.

what about: 'Cheaper doesn't mean slower'? It's pithier, and (in particular for anyone reading before/without looking at the page) better IMO in its place as a subheading. Scans better. Or even 'Cheaper != slower' (again, subhead).
