PS3 firmware 3.73 knows you've been too long bullied by all those firmware updates that require you to download them. But 3.73, he's different. He's casual. He's not a mandatory patch, he's completely optional. There's no pressure here, he knows you've had enough of that from those other guys.
But when it's time, 3.73 will be there. And when you're ready to accept his love, he'll be ready to improve the stability of "certain PS3 format software." Yeah, he knows that sounds vague. But girl, maybe that's exactly what you need.
