I'd say wait for the next iteration of the Nexus 10. It will be made by Samsung again as well as feature killer specs once more. The current N10 is still one of the top dogs in terms of specs so I am really curious how their next one will be.
However, as far as I'm aware the current N10 does not support 3G. Perhaps the next one will? Anyways, still reason to look out for it =D
