Would you use mobile device for m-learning?

My thought on this is that because a lot of people in some poor countries in South East Asia like Indonesia for example can afford mobile phones rather, then these users might use their mobile phone as a substitute of e-learning or distance learning, provided the internet connection is affordable and reliable.

Then, the other type of users would be the ones who use m-learning as a complementary say to do something useful while killing time say when waiting for the bus or in a waiting room or sitting in a bus/train. I for one hate it when I can't do anything else inside trains/buses or while waiting for one besides staring at something! (when I forgot my reading/music)

Some modules in e-learning can display basic media such as movie file or text file like a case-study (maybe pdf) that is put on a website (and some websites already make movie and text-based case studies available for free), basically to make it displayed easily. And these materials: movie files and text files can be displayed on mobile devices too.

So would you use your mobile device say as a complementary or substitute (say if you're on the move a lot or maybe for people who don't have computers which is not the case with Canada I reckon) to e-learning/distance learning?
Of course maybe blended learning is the best where you can also have a face-to-face meeting with the tutor or even to sit in a classroom, but this is a hypothetical situation say your only option is distance learning in any form, maybe for example being stuck in the most North part of Canada(?) (I don't think I want to imagine how cold it is when I was in Edmonton and Calgary in March year 2000, -12 degrees Celcius during the day was already very cold for me! Let alone Northern part!)

Ok, back to the original topic. Nothing much can be done on displaying a movie file or text file on mobile devices cause of the screen size (now who says size doesn't matter? ), but perhaps there is anything can be done to make the m-learning experience not so bad?
My imagination runs wild thinking it'd be cool if the mobile device can display hologram or like a projector to play the movie on a surface like a wall or white paper even to make the display size bigger, but then that's the geeky side of me talking!
