The default software is shit from what I've heard, but there's already a nearly 100% working ICS build, thanks to kernel and driver stuff from nVidia.
If you're willing to flash a custom ROM, I think it's great value.
Of course, I don't know about the Austrian phone market, but sale-point sells it international, for 270EUR. So maybe there's something better for your range.
Edited:
Alternatively I think the Nexus S is in that range. 280 EUR at sale-point
Why does everyone keep comparing the O2X to the Nexus S? It's like comparing the Galaxy SII to the original Galaxy.
