Iolo Technlogies, which sells PC tune-up software, said its lab unit found that a brand-new machine running Windows 7 takes a minute and 34 seconds to become usable, as compared to a minute and 6 seconds for Windows Vista. Iolo notes that it measured not the time it takes for the desktop to appear--which can be as little as 40 seconds on a fresh installation of Windows 7--but rather the time it takes to become fully usable "with CPU cycles no longer significantly high and a true idle state achieved."
