Swivel It: Danger Hiptop (2002)
Before the T-Mobile Sidekick became Hollywood's "it" phone, it was known as the Danger Hiptop. US PC World liked it so much that they named it product of the year in 2003. While its voice capabilities were only mediocre, this was one of the first devices to offer truly functional mobile Web browsing, e-mail access, and instant messaging. Plus, it pioneered that nifty swiveling design.
