PC World’s slideshow Slate Wars shows 15 potential rivals to the iPad. I don’t agree with some, like the Dell Streak (a 5” phone isn’t really comparable) or the Microsoft Courier (no sign it ever will be available). But others, like the Notion Ink Adam or an Asus device, appear to be in the works. All are supposedly available this year, some possibly as early as June. So for those like me who are resisting (so far) the iPad KoolAid, there is hope of ADT (Alternate Device Therapy) soon.
