[jQuery] Set element's css 'min-height' to browser's viewport height?

Hi!
I'd like to set all elements with the class ".inner" to have a minimum
height equal to the height of the browser's viewport. So, if the
window height is 550px, each of the '.inner' divs will have a minimum
height of 550px. I suspect it's bound to be super-easy to do with
jQuery, but newbie that I am, I can't figure it out. :-S
How would I go about doing this?
Many thanks,
Zarino
