"Getting on the train, opening your bag and realising you forgot your book." many is the time! That said (and I expect you guessed someone might say this) since I have largely moved to e_reading, it's a thing of the past I still live the reader at home or work sometimes, but for that journey I can whip out my phone and continue where I left off - that is just too good. Small phone screen not ideal, but for those once off situations it's absolutely fine
