I've been using my iphone to run dice rolls lately, with the app "Mach Dice". It's very helpful since it lets you roll large numbers of dice and it keeps track of how many times each number come up in a roll (6x4,5x2,4x1,etc). I find rolling the dice in cramped quarters to be annoying, especially when you have to do multiple rolls for large numbers.

There are a ton of dice apps in the app store, mostly for D&D use, but i was wondering if anyone else had tried this or come across a program they could endorse.
