Asus.

Does the job for me. Was using it in conference today to make notes on Evernote.
"Swiping" words on the Google screen keyboard was actually quicker than my pen and paper which is not bad for non-typist 58yo me. Hardly any corrections required.

Don't get me wrong, an iPad's a nice bit of kit and I might have bought one but I ended up with the Nexus 7 by default and don't feel like I need to change.
