ebook at ebedtime

Whilst there are still physical ink-and-paper books sitting on the shelves unread since they were bought alongside gifts-for-others from winter festive period 2009 I've managed to read a few others electrically, whenever an odd moment is available, such as when listening to check that Edgar is going to sleep and isn't trying to climb out of his cot or induce vomiting. Whilst I still want to read those I've already bought in hardware form I don't want to buy them again in e-readable form, nor sell the physical copies in order to fund their re-purchase electrically.
