Acer, Asus and Lenovo will reportedly begin selling ultrabooks equipped with Intel’s fast and versatile Thunderbolt I/O port, which combines DisplayPort and PCI Express, during the second quarter of 2012. DigiTimes said mostly high-end computers will adopt Thunderbolt this year since it now costs more than $20 to add Thunderbolt connectivity to a computer. Apple was one of the first companies to adopt Thunderbolt and it currently equips a number of its computers and displays with the technology. A recent patent filing also suggested Apple may begin using Thunderbolt in iOS devices, too.
