My Daughter Sarah, bought me a Kindle 4 for Christmas, i find it is really good. I have quite a few of the "classics" on it and some other books i downloaded. Also i have all SPRATS from 1-140 on it. I edited the pdf files using adobe professional v 9 and reduced the file size so they only take up about 350mb. They are all easy to read. Nice having them all there pocket size :-)
