Its not just the US versions, I have a UK version and "Just Type" also defaults to Google USA. I have tried a number of things including forcing the Touchpad to add Google UK to the search engine list. But on execution it still defaults to the USA.
I gave up and would be very interested to find a solution.
Excellent tip. Worked a treat for me although for some reason I had to install SDK to get my PC to locate the PDK. As a result there was some initial head scratching. However, this has solved the only real niggle on the touchpad for me. Many thanks!
