There’s a good chance your smartphone has more processing power than a 1985 Cray-2 Supercomputer. What it doesn’t have is a display big enough for a spreadsheet, or a keyboard good for more than cramped fumbling.
Enter the Superbook, currently available for $99 through a Kicksterter campaign. It looks like a slim laptop, but it doesn’t have its own storage or processor. Instead, it gets its power and data connection from your Android phone, via a simple USB cable and a free app. In addition to the keyboard and screen, the Smartbook has a battery, which will last 8 hours and actually charge your phone as you use it.
Together, a phone and the Smartbook are plenty for basic word processing, email, and web browsing—all most people really need.
