It is a big ask to expect to complete a module entirely on an iPad - I suppose the greater challenge would eb to do so on a smartphone. My first and thus far ONLY trip is that I cannot edit a wiki. The advantage is making use of micro moments, on a bus, waiting for a bus, in the bath (oh yes), a passenger in a car - breaking from a walk. All occasions when a laptop, even a netbook, is too bulk or slow to open.
