I've had my Kindle for years - can't remember how old it is, but it's probably 8-10 years old. As far as I know it's not full - but how would I know?! In my home page I have 36 pages, and 357 items. I have 81 archived items.
What's started happening recently, though, is that when I buy new books, some get downloaded on to my home page but others get downloaded into my archived items. There seems to be no rhyme nor reason why. As an example, tonight I bought 6 new books, and only three went into my home page - I had to retrieve the others from archived items.
Any idea why this might be? Or is it simply that a) it's full and/or b) it's too old and is dying?
