This is more of a statement really... I was curious as to whether the Tap 20 would support WiDi as it has the correct chipset but there seems to be no details on the website or reviews...
However I bought a Belkin ScreenCast in the vague hope it would work... the Sony provided WiDi drivers didn't work at all, but after I upgraded the screencast box's firmware and downloaded the latest Intel drivers I was pleased to see that it worked!
Its a great addition to unit as I can now browse on my lap and everyone can see without crowding around - a very nice feature which you (Sony) should shout about! :
PS Still need a case in the UK though :
