Well, try to read more carefully Device''s OS is not WinCE...from their mother site, info is "Windows Embedded Handheld"
Similar to CE, but not same...
Although by definition they should support the same applications, it doesn't have to be the rule. It is very possible for the device manufacturer to prohibit the use of others.

And, don't use iGO8, try Primo.

I didn't find any info about CPU architecture, I would not be surprised if it comes to MIPS.
