Is there a way to pay for apps with paypal? Is there a market where I can buy apps with PayPal?
Will the original Market going to support payment with PayPal?

Thanx.
With the recent legal bickering between eBay and Google, I'd say that the Android Market starting to accept PayPal (owned by eBay) is highly unlikely any time soon:

There are other alternative markets like SlideMe that I believe do offer PayPal.
