ISO is film speed. To over-simplify a bit, lower is generally better if you don't want grainy photos.
The 870 has more resolution options, a larger LCD (preferred IMO), is a bit lighter and has a different zoom range. The thing the 850 really has over the 870 is it does time lapse recording and can zoom more (at the expense of less wide zoom).

"Here, at last, is the cure for texting while driving. The millions of deaths which occur every year due to the iPhone’s ability to stream the Kim K/Ray-J video in 4G could all be avoided, every last one of them, if the government issued everyone a Seventies 911 and made sure they always left the house five minutes later than they’d wanted to. It would help if it could be made to rain as well. Full attention on the road. Guaranteed." -Jack Baruth
