Personally I would go with this.

I have one for trips and it runs just fine, takes a while for it to charge because it charges as if its a tablet. It uses Windows 8.1 so you can install regular PC applications on it and I have seen reviews of it running WoW so it should be able to hand EQ just fine (haven't tested it myself yet). Plus it is MUCH cheaper than a surface.
