But don't panic. As a beta user, I've seen the preview version get better and better over time since its reveal last year. Most, if not all, functionality from the original map is back, but with a slick new paint (which may cause performance lags if your computer is ancient, especially in Google Earth mode). However, the controls and the way it displays information has been rejiggered a bit. It's a lot similar to the mobile app, so it shouldn't look too unfamiliar.
