According to PC World, Google Earth is the best software product of 2006. It’s listed 6th overall in the magazine’s 100 Best Products of the Year.
Products one to five? Intel and AMD chips, Cragslist.org, the iPod Nano, and a Seagate portable hard drive. None of those, to the best of my knowledge, have their own dedicated blogs:-)
Note, however, that Microsoft Virtual Earth makes it to the list (#39) whereas Google Maps doesn’t. The review of “Live Local” cites the bird’s eye view feature.
