either that asus transformer or acer aspire switch. the first can sometimes have a extra battery hidden in the dock, the other an extra 500GB drive - so it's really up to your preferences...
ps: if you get the later one, the first thing you should do is remove acer user experience improvement crap and the mcaffee antivirus /you can use comodo firewall and avast as a substitution/. doing that will free a substantial amount of ram.
