How long after launch easily buy 360?

[2ZeBeach]

I was wondering since the Wii is pretty much sold out everywhere three months after launch and I wanted some comparison....How long after the 360 was released could someone walk into any game store and easily find one?

you really cant compare that, each system has its different stats and demands in certin areas
360 didnt do well at all in japan so there wasnt much demand
it was sold out though for a good 4 months i believe
