The Achilles heel of the iPad from the beginning has been the difficulty of input compared to the laptop. You could use a wireless keyboard, but this really takes the tablet out of its element and gives you two pieces of equipment to port around that makes it questionable to compare it as an advantage to a laptop. A revolutionary product has debuted to counter this trouble.
A startup out of Redmond called Touchfire has created the perfect keyboard overlay that gives you the tactile feel of the keyboard, yet making it almost nonexistent with the ability to roll up and slide off the iPad.
An education development company, "Typing Agent", is the first to offer an online version of their keyboarding tutor for schools that is compatible with the iPad. With the combination of a Touchfire and Typing Agent, a student can seamlessly move from a lab to an iPad to continue their typing.
