Saw this (via Hankers News Service) on Neowin.net in an article by John Callaham:

We’ve seen all-in-one PCs that have the parts inside a monitor.

We’ve also seen media center PCs that hook up to larger HDTVs.

Now one company is working on a prototype product that creates an all-in-one PC on a truly massive scale.

Dvice.com has reported that the German company Hannspree showed off the Lounge TV 70 at this week's IFA trade show in Berlin.

The product shown at Hannspree's booth was a massive 70 inch 1080p HDTV that also had a PC running inside it with Microsoft's Windows 7 operating system. Once more, the TV was running a business app that allowed people to "draw" images on the huge TV screen. So, that turned this TV-PC combo into a whiteboard as well. Could be very helpful if that could be transmitted as well.

The story speculates that this kind of product could be used by businesses for high end presentations in conference rooms.

The report did not have any information on the PC’s  specs.

Usually, the PC’s are low end in the specs department, but how cool would it be to see a high end PC merged with a big screen TV like this for gaming?

There's no info on availability nor production dates.
