Wasn't me either. I briefly considered it, but passed. I figured that it would be one that certain domainers would go after and run the price up to more than I'd be willing to pay for it, and I was right.
Canadian usage is like 10 to 1 in favor of TakeOut vs TakeAway. Note that TakeOut is the north american variant (US and Canada), TakeAway is the Brit/Aussie variant.
The one thing I say it has going for it is that it rhymes with the .CA . Take-Away-dot-cee-eh. Would make for a better jingle or something. But it would also require more effort to retrain canadian thinking.
