The Boogie Board Jot 8.5 aims to create the most natural pen on paper writing experience of any eWriter in the world. It is very light, much lighter and thinner than my normal notepad which slides its way down the fridge, at a feather light 0.3 pounds and 0.6 inches thin, there are two built in magnets on the back that can hold it in place on metal surfaces and it comes with a replaceable coin-cell battery that lasts up to 50,000 erases.
