A power cut. I use the iPad as a torch to locate matches, have candles on the dining room table and the gas stove heating up water. I don't need to rummage around for a book as it is loaded into iBooks. I'll see where 3 hours reading and note taking gets me (Part 4 of Book 3 I hope) then off to Surrey and a tutorial. Although a came to an MBA module as an elective of the MAODE I may well do the entire MBA as for the fourth time I may be going down the route of setting up my own business.
