Here's a way to start the new year right. Before you decide to buy yourself an e-book reader, ignore all the hype from Amazon and Sony and all the others and take a look at what may be the best buy of all, The eBookwise-1150. It's a compact reader that has lots of good features, holds lots of books, fairly easy book buying capability and it's under $100!
You read that right. The 1150 sells for $89.95. It's the closest reader to my old favorite the Rocket e-book. It's the only one that's backlit as far as I can tell. I love that feature. Check out http://www.ebookwise.com/. I own a Reb 1100, which was the precursor to this device.
While it's not as flashy as the Kindle, it's a solid workhorse and will serve you well, I think. It will read multiple formats, including files you've created yourself, without a lot of fuss and bother.
A good way to start out the new year! Read on!
