This month's hardware pick is considerably cheaper than last month's iPod Touch. It's a stress ball.
I know what you're thinking, it's almost the end of January and at the last minute I'm giving you a stress ball because I couldn't think of a more useful hardware pick. And you'd be right. Nevertheless, the stress ball can be a valuable addition to every poker player's utility belt. It's main purpose: tilt control. When you flop the high straight with no flush draw out there and someone calls your all-in with two pair, causing you to lose on the river to a full house (and yes, it happened to me yesterday) don't get mad, don't get even...get a stress ball.Although I'm making no guarantees that you won't still fume for a while, results may vary after all, but a little ball to squeeze out the tension can make you feel a lot better. It can also make your opponent feel better now that you are inflicting violence on the ball and not on him.
Don't knock it 'til you've tried it. Besides, it can double as a card guard.
