No need. Apple released a cover with their iPad 2 that has magnetic catches (which Microsoft demonstrated that will be available for the Surface). I have found the magnetic catch system very useful on my iPad. The iPad cover folds into a triangle to support the iPad in landscape mode. Detach it by pulling the magnetic catches away, then lay the iPad on the triangle support in portrait position. Kudos to Microsoft for building in the kickstand; however, it won't help when you want to position the Surface in portrait mode at an easy angle. There are many external keyboard solutions already available for the iPad, even keyboard covers available from non-Apple sources.
At an easy angle? Whats that even mean? As far as the keyboard/cover thing goes..it’s designed with the surface and not secondary to it. In fact you won’t need a dongle or anything because the magnetic clip part is also a data and power port..Apple does not have that..and the keyboard attachments I have seen for the iPad aren’t really that impressive.
