Technology changes in the blink of an eye. Take the lovely Kindle. We were comparing them today in the library and then comparing them to iPads. The geeky fun we have! So the tall Kindle DX from 2009 belongs to the library, the middle one is my Kindle Paperwhite from 2012, and the last one, the Kindle 7, is from 2015 and belongs to my student. Its amazing how far their size, shape, memory, e-ink, touchscreen, and weight has changed in just a few years.
