Personally, I like a bit if info. Emphasis on a bit. Where it affects the story it's essential, obviously. If you have a one armed assassin it needs to be mentioned because the reader will be thinking
"Why the hell isn't he stabbing him with his left arm" in a close encounter where it's blatantly obvious the victim should be dead by now if he had a spare hand etc.
Also it’s nice to have a rough idea of the appeal of the characters to other characters. So if our hero is a handsome brute with dashing features and there’s a radiant beauty he flirts then it adds credence to know that rather than him/her looking as attractive as a pig with acne.
Of course if you think at some point in the future you have the makings of a JKR or GRRM film, it’s better to get your impressions down so the reader will know what to expect in the movie. Rather than have a skinny dweeb playing your brutish thug.
I believe this happened with a series of detective novels that was shown on TV. The main character looked nothing like the picture the readers had built up in their minds and it completely ruined it for them.
And I agree with
@sknox's point about features being a good way to have a way of refering to them.
As in if our hero is a overweight red haired dwarf it gives the perfect way for you to start a fight in the tavern scene.
"So you're Twinkie," said the stranger, "I've heard a lot about you Twinkie."
Twinks looked at the stranger and sqinting through his blood shot eye he asked. "Oh yes what have you heard?"
"I've heard you'e the red haired no good son of a wombat."
And off we go into the big punch up scene.
