been looking at ereaders for a couple of months only just got past the thought process of them being a gimmick, but my ever expanding library is now conflicting with a lack of space caused by my wifes house renovation plans and my 2 four year olds stated intent to single handedly support the global toy market, so this seems like the perfect solution..... mmm 511 for £129 at waterstones or the 600 for £149 at ASDA direct...decisions decisions, any thoughts???
