If there's any doubt that the iPad is a hit, that can be assuaged by looking at the number of iPad-like competitors hitting the market. Technologizer has posted a list, with images, of 32 "iPadversaries." The most astonishing is the Toshiba Libretto W100. It actually has two screens joined by a hinge. You can perch it like a laptop, and one of the screens becomes a keyboard. Just think, a year ago this market didn't exist, and now it's exploding with creativity.
