You can't escape the iPad, and offers to receive too good to be true free ones, especially on Twitter where clicking a link to greedily obtain your generous gratis reward like Naomi Campbell at dinner with a Liberian warlord can lead you into trouble. Why the very fact you are reading this might well be because you were seduced by my apparent generosity. But it is all a ruse. I won't give you a virus like some but the link is merely a device to keep you informed about the latest portable device I am developing to shield you from the rain. Yes, later this year I will be launching the iGamp. My rivals claim that such a technological precipitation shelter gizmo already exists (the iMac) but the iGamp will blow this backward gadget out of the rain water with its mobility and functionality. Watch this space.
