I contacted Jointech support with a couple questions about the JE200.
1) Yes, it will be possible to upgrade the OS in the future to WinCE 6.0 and android on the same device.
2) The Wifi Dongle comes with JE200. I could not find a place to add the dongle to an order and it's not mentioned as an accessory.
If CES wasn't a week away and there weren't so many new devices launching in 2010 I'd order one tonight. However, I'm going to be grown up about this and be patient... but it is so very difficult. Every night when I have to turn on my silly headlamp to read in bed I remind myself that it won't be much longer now.
