I’m not a fan of credit-cards. Personally speaking, I think Paypal, despite all it’s flaws, is the slightly lesser evil.
Paypal gets the one thing right about payment online: Don’t allow charges without user authorization. That’s where credit-cards fall short, in my opinion.
Needless to say I was quite disheartened to learn Bitcasa only allows credit-cards as their method of payment (although the legal page hinted strongly towards that during beta). Luckily enough, services like Kalixa, Wirecard or Neteller seem to work fine with Bitcasa. While not a perfect solution, this does at least postpone the problem a year for me.
Once again, Wuala gets it right while others seem to fail miserably with the same tools at their disposal: Paypal recurring, Paypal subscription (usable without credit-card) and even Bitcoin are offered as payment options.
