Welcome to MobileRead, oldlady!
Although to the lot of 505 owners here, color seems to be an issue, I have a Sony 700 which only comes in black. I'm not sure what that means, but there ya go?!?!

I am sure you will love your reader as much as I do mine and will become an ebook addict before long. Thankfully, they DO NOT have a 12 step program for that, so it's all good! Be sure and take a look at all the free ebooks you can download here at MR in the lrf format you need for the Sony. Enjoy!
Happy Reading.
