Speaking as an ex-hardware guy (albeit a few years ago <cough> ) I think it unlikely that Microsoft designed a tablet which couldn't use Bluetooth and WiFi at the same time, given that this is the third version of the Surface. Also, as has been said in this
forum, it can be resolved by giving the Surface to wife and using an iPad...
I accept that a badly designed radio transmitter can bleed all over the spectrum and interfere with other devices, but walk around Microsoft Thames Valley Park, and you'll see these things all over.
The surface pen is indeed Bluetooth, it appears in the list of Bluetooth devices underneath the Tecknet Bluetooth mouse.
I've just been to see Scott Guthrie give an Azure presentation in London, he was using his Surface, and I think one of these "Universal" keyboards, with the Microsoft wedge mouse. He was poking Azure over the theatre WiFi.
Mine was working OK, I edited a Powerpoint on it a few days ago. Now its a dead parrot. Tomorrow I'll try it with my iPhone and someone's 'droid tablet, that should be the final word, I suspect its a return to Amazon.
BTW LegacyOfHerot is my screen name.
Hmm I just had a thought, I'll nip out and see if the Audi sees a Bluetooth device when I open the keyboard...
