No. Their WinCE laptops run on an ARM processor, while the Linux laptops use a MIPS. The OS can't be exchanged.
That's true. However, theoretically, it is possible to create a working Windows CE enviroment for the Ingenic Jz4730 MIPS CPU in the TrendTac. If anyone's planning to do so, I'd suggest to keep in mind that you can only install applications for MIPS, only files in the "My Documents" folder are saved after a reboot, there's a lot less things you can customize, and you are - strictly spoken - illegal.
So in fact you must be happy to have a Linux version
Oh, yes, about the ActiveSync cable, I think the people who have build-in their WiFi-dongle in the TrendTac, have used this port
