I remember the days when the entire BeOS operating system could run in 4 megs of ram. An application launcher running in 12.5 megs will never count as 'very little memory' to me.
My point was how little memory Alfred uses when compared the Quicksilver or Google QSB (the latter currently taking up 39MB at the moment).

It is a matter of perspective, not correctness.
