I just want to clarify something - some services offer PayPal to BTC conversion and you will most likely be able to use PP to purchase BTC that way.
However, PayPal is treating Bitcoin as foreign currency and in their ToS you can find note that using PayPal as a currency exchange is prohibited.
If they somehow discover that you purchased bitcoins with your PayPal your account will be frozen.
Coinbase buys bitcoins from people using Paypal now. Here's an article on that:
