Hi Frankie,
From watching my learners working on iPhones, iPads, Android phones and tablets, and Blackberry devices, I have to say that as ad-hoc devices, Android and Blackberry work pretty well for creating multimedia content (photos, audio and video) and uploading them onto a CMS/LMS. It still involves them going into an ICT lab and using PCs with full sized screens and real keyboards, so it's not exactly BYOD. However, some tried using tablets alone to update or write posts (I can check the IP addresses and server stats for that data) but they were short and I could see that they'd spent less time on them than those they'd authored on PCs.
