If there's something wrong with downloading; the Kindle keeps working away and away;that takes a lot of energy as well, and your Kindle will be unstable.
I have 1200 books on my Kindle and my Kindle isn't slow or doesn't crash.
Try calling Amazon again, as the quality of their technical assistance differs; though they are always friendly.
Hi - more often than not, my books are sideloaded. In fact it's pretty rare that I bother turning on the WiFi to download books directly from Amazon.
