3. Motorola RAZR
While most of the cellphones that came before the RAZR were thick and clunky, the RAZR was a flip phone that was thin and futuristic. Introduced in 2004, the RAZR was the cellphone that everybody wanted thanks to it flip phone form factor, its color screen, its camera, and its selection of ringtones. It was one of the best-selling clamshell-style phones, and just about everybody knew someone who had a RAZR.
