Intel unveiled at a conference a future concept of Ultrabooks that are convertibles.
The first round of Ultrabooks have been officially announced at the IFA 2011 last week. These new laptops are very thin and still run on the latest Intel Core i7 CPUs and offer decent battery life. If the price will be under $1,000 is still not sure. The first wave of Ultrabooks might just be a test as manufacturers are limiting the volume to 50,000. In the meantime Intel already shows where Ultrabooks are going: Tablets. Basically there will be Ultrabooks that feature a convertible design. This is nothing new. There are conventional laptops with a twisting touchscreen. The difference is in the measurements and price. The convertible Ultrabooks are still supposed to be very thin.
Ultrabooks are aimed at competing with the MacBook Air. I do not think that we will see a MacBook Air with a touchscreen though from Apple.
