Ensure that Google search always defaults to google.com and not to google.co.xx

Ever experience a wee bit of irritation when you type google.com and the search page redirects itself to google.co.xx (xx being the country you are currently in?)

If you DON'T want this to happen, simply type /ncr after google.com

(http://www.google.com/ncr)

and you'll get the familiar google.com search page.
