this keyboard be cheaper than its Sony brand competitor for a excellent reason - it be simply not as good . I be a fairly good typist , and this be \* much \* slower than use Graffiti to enter information .  you have to poke and push very hard to get the keystroke to register , and the divide nature of the keyboard make it very difficult to get up any speed at all . I could not type more than a few word without have to go back and add miss or extra letter .  I would only recommend this keyboard if you can not cope with graffitus at all . enter any large amount of text will simply take you too long and drive you insane with the pointlessness of become a two-fingered typist otherwise .
