The limited edition 21 Blackjack watch by Christophe Claret comes with a pair of dice, playing cards and a roulette wheel on the back. All the games are fully playable. (Thanks David!)
Short of hiring a dealer, getting this gizmo is the best way to speed up your games. It deals cards up to 3 feet away, guaranteed no flipping. Less waiting, more winning. Runs on two AA batteries.
