Ask David Pierce, What Windows 8 device will be your next?

As a follow up to David's post that Windows 8 will be his next I'm curious to know if he is any closer to deciding what device he'll buy at the end of the month?

From the devices that you've had hands on with do you have a favourite? Will you consider a SurfaceRT? What is your ideal formfactor / specs?

Please keep us updated, a lot of us won't have the opportunity to try out so many devices so I'm very interested in your opinion.
