I've owned this product for about 18 months now and never being an organised photo person this is perfect for me.
I particularly find it useful when visiting my 94 year old grandmother as I can take pictures of her and my children and print them off before I leave. She thinks this is brilliant. I also live halfway up a mountain so don't have to bother with finding somewhere to print photos to pop into birthday cards etc.
I also usually load them onto the PC and send them in e-mails.
I agree with everyone else that the cartridges are too expensive. However, Amazon does it again - less than half the price of getting it on the High Street for a printer refill. Bargain!!
