This integration has long been in discussion but i don't know why it has yet to be implemented. I think it's good for both sides paypal will benefit from btc users vice versa we want to be able to pay using btc at large marketplace where paypal is dominating. Hopefully we can see this become a reality by end of this year and if it does it's going to be a major boost for bitcoin adoption.
I agree with you.
If PayPal and Bitcoin partner up, it will benefit both sides but paypal CEO may feel that they don't need BTC, because we are still ''small' comparing with them.
I hope that they will see ''bigger'' picture and understand great potential of BTC or someone else will replace them and accept bitcoin as partner.
