I've been having a hell of a time finding a copy of Puzzle Quest anywhere, which only adds to my garment-rending grief about the lack of a true PC version. I'll find it eventually, but I think I might avoid the PSP version, at least for now. I had intended to do so for purely ergonomic reasons, believing a stylus was probably the ordained interface methodology, but there is a bug that negates companion bonuses on the Playstation portable that I am keen to avoid. I was worried about crowded screens full of text wrestling for space on the DS, but Gabriel says that they've experienced no ill-effects. I understand that he brought it home to Kara, suggesting that it was essentially a Bejeweled RPG, and now the two of them have hunched over those two screens every night since he bought it.
