The ASUS Eee PC (¨Eee¨is pronounced as ¨ee¨ in ¨see¨, IPA: /i?/) is a subnotebook / netbook computer by ASUS and a part of ASUS Eee product family. At the time of its introduction in fall 2007, it was noted for its combination of a light weight, Linux operating system, solid-state drive and relatively low cost. Newer models have added the option of Windows XP operating system and traditional hard disk drives. Newer models have also increased in price, though they remain relatively inexpensive as laptops, and notably inexpensive for ultra-small laptops.
