Apen has unveiled the A2 Smart Pen that allows you to digitize and record writing and drawing on a standard paper. You can also connect the A2 to a Mac or Windows-powered computer for writing on images, Microsoft Office documents, or Outlook messages. The gadget uses a wireless receiver that clips to a sheet of paper, providing a storage capacity of 100 pages before content must be transferred to a computer. The A2 Smart Pen will be launched later this month for $100 each. [Electronista]
