Hi! I know that MacWorld is long gone, but here are posts that were created at MacWorld, but sadly not published due to omitted information.
Here is a picture of Axiotron’s booth:
This company is the first to create a commercially available tablet Mac! Of course, this is a 3rd party modification to the plastic MacBook. They take the MacBook, remove the screen and turn it into a slate styled tablet. The Axiotron ModBook even has a built-in-GPS! The Modbook costs $2,250, and you can see all of it’s features etc. here: http://www.axiotron.com/index.php?id=modbook
But the big announcement was the ModBook Pro which features a 15 inch touch screen, but it costs $5,000-$6,000!
