It's a fair bit smaller than the current MBP touchpad. More like older MBP models. I don't like how gigantic the current MBP one is. Apple does a good job of ignoring rogue palm touches, via software, but in a way that makes it unresponsive when you want to do keyboard+touchpad combinations (which are rare, but important in some drawing apps and some games). Overall I find that I don't need that much touchpad real estate.
