I've updated the Windows CE history overview and thought I'd provide some trivia for you.
The codename's of the Windows CE Host Synchronisation software were also based around a mythological theme, just like the CE versions themselves.

Handheld PC Explorer 1.x - Codename Pegasus (The Winged Horse. Pegasus is the same code name as CE 1.0x)

Windows CE Services 2.x - Codename Minerva (The Roman goddess of wisdom, invention, arts, and prowess aka Athena)

ActiveSync 3.0 & 3.1 - Codename Xena (Someone's been watching too much Television)

ActiveSync 3.5, 3.6 & 3.7 - Codename Medusa (The Gorgon who's hair was of serpents & turned all who looked to stone)

So, who said Microsoft don't have a sense of humor. For more on Windows CE codename's, see:
