I ran across the following news at The Mobile Hornet.
"HTC is announcing the acquisition of the San Francisco based firm One & Company Design, Inc. (One & Co) furthering HTC leadership in design and innovation. One & Co was the company that introduced the iconic design of the HTC Touch Diamond. By acquiring One & Co, HTC world class product development will be further enhanced by creating one of the most advanced mobile design teams in the world."
(I personally think that the diamond is too small and since it doesn't have a built-in physical keyboard - the small screen size makes it way too hard to type with the virtual keyboard).
"Recognized for its award-winning work with some of the world best known and most design-savvy lifestyle brands, One & Co will maintain its name and client base while it joins forces with HTC to create an unparalleled force in global mobile design. One & Co has been recognized by the design and business communities by winning numerous BusinessWeek/IDSA IDEA Awards, the Good Design Awards, CES Innovation Awards, and ID Magazine awards."
