HOW IS IT DIFFERENT FROM A LAPTOP?
Laptops are still looking for a processor standard, but Ultrabooks will feature only second generation Intel Core i5 and i7. They will also have integrated graphics unlike the dedicated graphics in laptops—this might not make it very popular among gamers.
Laptops have no restrictions of size, but Ultrabooks will be mostly 13 inches and at least half the thickness of a regular laptop. So, naturally, they will also weigh less, under 1.5 kg compared to the average 2 kg of regular laptops. On the flipside, you will have no Ultrabook options if you are looking for a 17-inch laptop.
