Google Street View is vital to me about once a month, useful twice a month, and cool/fun 365 days a year. This version is less cool, less slick, less friendly, less fast... but for what I need (spotting a driveway or lane that is hard to see overhead) it does the job!
And transit info is all there as well.
A good backup in case iOS 6 Maps falls short for me. Added to Home Screen!
I hope someday someone makes a much better Street View without all the blurry/unreadable signs, lens flares, awkward movement, and tangled intersection lines. (Flyover might approach that in some cases, but it lacks street-level fine detail.)
