Google Maps 5.0 (Android)
As a loyal iPhone user and Mac-head this is not easy for me; but here goes.
Google Maps for Android 5.0 looks amazing. Frankly I think that much of what Google does these days is a footnote to its search and advertising empire ... but this is potentially huge.
And when a company can actually say that it offers 3D real-time mapping on a mobile phone, well, they're entitled to their accomplishment as a game changer.
So check out this video for a closer look at the technology and prepare to be seriously impress.
P.S. Apple, please take the hint. iPhone is beginning to look a little shabby here. Be careful or Google may eat your lunch ... again.
