Acer took advantage of the attention from the Computex show in Taipei this week to attack Apple directly in a stairway ad for the Iconia Tab A500. Those visiting part of the metro saw a two-part ad on either side of a staircase. One side seen by Engadget asked in Chinese why anyone would choose an iPad when it lacks an open OS, a high-resolution display, Dolby Surround audio, the Flash plugin, a microSD slot, or USB; the opposite side, as expected, touted all of those features on the Iconia Tab.
