i do the same as well. accidentally bought a few copies of the book by the same author;)

anyways, i voted for >500 since i don't exactly catalogue all my books but i can assure you i've got books lined up in the living room, outside my room, in my room, on my bedside table, in my hometown etc.

the bad thing is those in my hometown were 'attacked' by termites. almost cried but what else can i do. just burned them to ashes;)

now am looking forward to Kindle but sadly they still won't ship to M'sia via the new International Wireless thingy:(
