Google's Click To Call In UK

I reported yesterday that Google seems to have launched Click To Call in the UK. A search on jet2 should bring back an ad from Directline Holidays with a green phone, clicking on the phone will allow you to enter your phone number for a call back from that advertiser. Click to call was launched by Google in the US in February 2006. I have screen captures and more details at the Search Engine Roundtable.
