Well don't blame me for this, blame the fine upstanding member, rossjackson01, he made me do it.
Anyway we are all here for one reason, we believe the pb works for us. The problem being that it could potentially have been great and IMHO far better that the ipad so then in its basic form why do you think it failed?. Now it's time to find out for real.
Please do not try this at home without an adult present and a safety net.
