Puzzle Quest ordered

I couldn't help myself. I ordered Puzzle Quest from Games Warehouse for $19.99 (but it'll be more like $26 after shipping and handling). The game looks like the perfect game to play when you've got a spare 5-10 minutes to wait but not wanting to commit yourself to a game that requires more time (e.g. a Guild Wars Tombs Run). I've heard generally good reviews from the press (85% from GameRankings and 84 from MetaCritic) and my girlfriend is addicted to it - but not so good reviews from co-workers (I'm actually surprised at how many people are playing it).

Unfortunately it's currently out of stock so I may be waiting awhile.
