Welcome to MobileRead, Lucy!
Congratulations on your new toy! I have the Sony 700 and absolutely love it and dread it when I have to go back to reading paper anything (do you think my daughter's teacher would be willing to send notes home formatted for my reader?!?!

)! Anyway, I'm happy that MR was able to help you with your decision in buying a reader. Don't hesitate to ask questions when they pop-up, and they will!
Happy Reading!
