Thanks all for your answers. I too remove the DRM as soon as I get a book. Mainly as some have said to protect myself in the future to make sure the books I have today are able to be read on whatever reader I get in the future. It is second nature. But, I have been only putting non amazon DRM free books on my kindle and having the DRMed Amazon books sent directly to the Kindle. Probably in the back of my mind I was wondering if the 'Amazon ereader/ebook Police' would come and cart me away. Of course my husband would say, 'don't worry, after they've had you for a few hours they'd ship you back'. They wouldn't be able to stand me.
It really would be easier to do everything from Calibre. Thanks to all for enlightening me.
