I understand where you're coming from, but I really think there's more to it then you say. Like a lot of people I know, I bought a ps3 -because- I could develop games on it. A year later, sony takes it away. I don't play on-line (and that's a concious choice), but since they started introducing games where you have to go on-line to play, I refuse to buy them. And now, with the network breech disclosing information I *would be required* to provide to play newer games, I'm sorry -- I will probably never buy a sony video game console or game ever again.
As for the 360, yeah Microsoft is hated by one and all. Not just for the RROD problems, or even the charges for the Xbox network games (though from what I've been told, you aren't -forced- to pay for their network; it's an 'upgrade' to standard service. Maybe things have changed recently.). But in their favor, you can develop for the 360 cheaply, RROD's got fixed promptly (and the warrentee was extended) and you know Microsoft can afford to fix things when they go wrong. Heck, I'm not even sure they ever made it into the black on the 360 yet

As for PC's and the wii....Not really a factor. Though if Nintendo takes a chance and creates a better Wii2, they might take the next round

Personally, I think a lot of people are gonna be wondering if it's worth the risk to play on-line. If anyone does anything with the stolen info, a lot of people are probably just gonna decide it's not worth it, and drag out their old consoles when they want to play games

Also, keep in mind, it's not -just- that you can't play on-line for a few weeks. There's also the simple fact that now you have to worry about someone mis-using your personal credit info. Which is going to reduce to the simple thought of "No, johnny, you can't use my credit card. Sony can't be trusted to keep that info safe." for a -lot- of parents....
Just for the record: I actually liked the ps1 and ps2. Still play them quite a bit. My ps3...not so much. I'll probably just sell it to my friend who's 'borrowing' it now. Haven't missed it yet
