Total sales of thin client in the Asia/Pacific (including Japan) (APJ) market reached 279,513 units in 2005, representing an increase of 64% over 2004. Revenue likewise increased 65% over the same period. From an operating system (OS) perspective, proprietary OS rollouts see high traction in countries where local thin client vendors employing their own applications have a strong say, such as Korea and the PRC. The “others” OS category (including Sun’s embedded firmware) was the largest, at 34% share of the overall APJ market in 2005. Windows CE was installed in 24% of all APJ thin client deployments, Windows XP Embedded captured 22%, and Linux followed closely with a 21% share, IDC says.
