while i haven't seen much advertisement so far for the touchpad in the UK, carphone warehouse's effort seems to be quite good.. hovering over the 'tablets' tab on the homepage shows the touchpad as the 3rd option, over the playbook, xoom and flyer (obviously below the ipad but that is understandable) and the actual page for it isn't too bad either!

carphonewarehouse.com/ipad-and-tablets/hp-touchpad

it is also one of the top items on Curry's main tablet page..

seems to be a much bigger push than webOS has ever had before in our country. Well done HP for making an effort!
