Pros: Large screen was excellent for viewing graphs, PDF files
Cons: It is cheaply made, and not worth the investment.
I purchased my Kindle DX two years ago, paying $500. I noticed today the toggle switch cracked, turns out others have had this problem, but Kindle won't fix it. Instead, they want you to pay another $150 for repair/replace. So, I paid $250 per year to use this device. It is a rip-off. If you buy one, buy the cheapest one, so when the poorly made product goes up in flames, you are not out the way I am.
