Lenovo's PC updates on Tuesday were headlined by two IdeaPad notebooks that claim to be more responsive than even the MacBook Air. The 14-inch Y470, as well as the 15.6-inch Y570 and Y570d, each have the option of a 32GB or 64GB SSD for the OS alongside a regular hard drive. Along with Intel's new Sandy Bridge processors and optimizations to the boot process, they can start in as little as 10 seconds, versus Apple's 15 seconds, while still holding as much as 1TB of regular space.
