The point is that we could have a lot of good looking games in Maemo 5 in a short timeframe, lilke weeks or months, at an affordable price and with a low effort. One could probably finance such an effort using a minuscule part of the Maemo marketing budget (just think what adverts in The Times cost in comparison!)
Of course, in a mid- to longterm view, Qt/Orgre might well be the better philosophical way to go.
