I think having an issue with the fact that iPads/Phones/Pods are so restrictive and then lumping in all SmartPhones and eLearning platforms with that experience is just a little sweeping generalisation, don't you?
Although, if your point is that iPxxxxxs (or any other specific technology which blocks standard uses rather than allows variety) get in the way of lots of things then, yes I agree - I have recently had a number of students telling me that they can't be bothered bringing their iPads to lectures or getting them out for working on, because they know they can't access content properly, or do the tasks set for them on their iPad - The flexibility is no good to them if they can't access the materials when and how they want anyway, while friends with supposedly more basic netbooks/smartphones (linux/android/winxp) are able to access those materials in lectures, around the campus etc.
I can easily bluetooth files from my my moodle course to my (relatively low-spec) htc android phone and back to another non-internet linked laptop when I need to (I'd left my usb memory stick in work last summer and wanted to work on some files while I was away in the caravan with no internet access - there is a logic in there somewhere! :D)
Having to redesign existing course materials for a specific platform (whether that is the iPad, or people still being forced to use IE6/7) can be a major hurdle for tutors who just want a straightforward way of delivering online content which their students can access. Of course, new content can be designed to cater for those needs when it is being developed, but in so many cases, material often already exists and staff want to use it and deliver the teaching and learning and not spend additional time redevloping content they already have in Flash or other formats.
