I tried it, but not of the versions of Opera would load or run. I get the same problem with it on my Neta 980 that I get on my CE6 netbook. It goes to the main loading screen and just keeps trying to load and trying and trying and trying....
My experience on the Viewpad with WinCe 4.1 is identical. with wince 3.0, I managed to get connection to the main opera server. When I accept the EULA, it shuts down.
