This is an AnandTech review of the Hypersonic Sonic Aviator 3.06GHz Pentium 4 laptop which is just another rebadge of the Clevo 5600. I bought mine (rebadged as a Promedion) a while back, but with a 2GHz P4 (Northwood) and a Radeon 7500 Mobility instead of a Radeon 9000 Mobility.
In case you didn’t know, this laptop does Linux.
