Google Earth (beta) is now up to version 5.0, with a bunch of news, as some may have seen. Among them:
- Historical imagery from around the globe
- Ocean floor and surface data from marine experts
- Simplified touring with audio and voice recording

Product Tour – New! in Earth 5.0 (beta): http://earth.google.com/intl/en/tour.html%5B/url%5D
I have only used the free version, but there were some more before, as you know; Plus and Pro etc.
As I understand it Google Earth Plus is discontinued (last year), however there are good news. Google Earth 5 Free now contains its features. GPS tracking is available in the free version; importing of GPS tracks and real-time tracking, as I understand it.
