The recent FAQ (2.2) notes that the text should read “Trash Q-Coherence Chip when an installed program is trashed.” trashing programs from hand is fine. Installing these could prevent the need to trash programs (intentionally), so this is more playable than possibly first thought.

More playable, sure, but still not very playable IMHO. The big problem, even with the errata, is runners frequently like to trash program X in favor of program Y, and this makes that so very painful. For 3 creds more you can also get +1 link with the exact same faction cost. —
