We purchased our middle daughter a Sony PRS-300 a couple of months ago for an early Christmas present. She is a voracious reader and after seeing both Mum and dad's ereaders decided that an ereader was for her.
Alison even took her ereader to hospital last week when her daughter (our fist grandchild) was born two months premature. (Both are well and her husband cannot stop smiling!)
Our youngest little lady (16 year old daughter) loves paperbacks and old books and has no desire as yet to move down the ebook path.
