The Kindle 3 (Keyboard) remains my choice of best all around Kindle ever. It was well built and had a lot of bells and whistles. The Kindles that came later on all have major compromises of some sort. Amazon decided to cut the internal memory, get rid of audio ability, et cetera. The newer Kindles might have better tech features and software, but I still think the K3 was the pinnacle of achievement in Amazon branded e-Ink readers. After the K3 Amazon started building their readers cheaper and cheaper, and it shows. The touchscreen models have never reached the screen quality they should have, and the K4s are scaled way back from the K3 feature set. The K4 probably has the best screen of all the Kindles, but the K3 is still the best overall achievement among Kindles, IMO.
