Flip Mino HD 2nd Gen VS Flip Ultra HD, whats the difference?

it's just basically the size, but i got the Flip Ultra HD just because it was able to shoot 120mins, and the first mino was only 60. but now looking back i should have got the mino because i find it very hard to pull it out of my pocket, so if you have the money i say get the mino just so it will be easier to handle
