The WinBook M Series laptops were value-focused systems with desktop Pentium 4 processors. They were based on the Mitac MiNote 8640 series generic ODM laptops. They were relatively compact laptops when compared against other systems with full-fat P4 chips, so I do have to wonder how hot they ran.
While WinBook's support pages just called these the "M Series", the order page on the main WinBook website showed model names similar to their other laptops. (M221, M200, M103, etc). The M1xx laptops had Celeron processors and the M2xx laptops had Pentium 4 chips. There were 8 total models listed, but I'm not listing them all here as a difference as small as whether they shipped with XP Home or XP Pro led to a unique model number. It seems to be more a way to track shipping configurations than anything else.
Additional details you can't see: power button has a brushed metal look (similar to a PowerBook G4), the entire outside is silver.
