Want proof of just how much app-based solutions can disrupt established businesses? Try the fact that Uber, the Android- and iOS-based alternative to traditional taxi services, has just been valued at $17 billion.
The valuation comes on the back of a new round of venture funding for the 5-year-old company, which saw investors pour in another $1.2 billion. This makes Uber one of the most valuable startups in tech history.
