Welcome to MR, craj999
I've had my 505 for a year now and absolutely love it.
Have you discovered all the beautifully, hand crafted free ebooks on this site? Some very dedicated MR members continue to add to our library. You can use the LRF and the ePub formats on the 505. Just look up on the left in the blue bar. You can choose a format to check out all the books available.
Have fun exploring the forums and ask if you want to know something.
