The flip phone reached its artistic zenith with Motorola's sleek and slim Razr, the thinnest clamshell of its time. Reigning supreme in the mid-2000s -- right before the smartphone went mainstream -- the Razr was a minimalist beauty well-suited for talk and text. As the decade progressed, Motorola released updated versions of the Razr, including models with touch-capable external displays. There was even a hot pink version that 15-minute celebs like Paris Hilton couldn't resist.

In 2011, the Razr brand was resurrected for a new line of Motorola's Android-based Droid phones.
