haven't read everyone's comments, but, this sounds like a bad idea to me.
Sony is sorta schizo because of their hardware side competing against their entertainment side. with the need to make money on both sides of the biz, there is some friction. by that i mean that the entertainment side is gungho about DRM. the hardware side seemingly isn't (this according to a couple of articles I've read in the past year). Apple is schizo enough as is. they are making hardware and software, some even for competing platforms (winders).
And The Big A does't seem to be increasing their coffers from year to year. Heck. alot of those quarters they had a while ago, during the Bubble, were the result of investment revenue. Don't you all recall how they had a huge stake in ARM Holdings and slowly sold off shares and added that to the bottom line?
Additionally, since Apple is trying to innovate their way out of the recession that means they are spending more and expecting to take losses. Why roll out jack for a huge purchase when the core biz isn't supporting it self as the company, and us people, would like it to? Misplaced priority. Totally misplaced. I'd rather think Apple buying specialty products developers, like those companies that make iPod accessories, or picking up assets from companies like SonicBlue (bankrupt) would broaden their reach in the established market and allow the company to expand their markets into general consumer goods. There isn't anything wrong with that and it would increase their stock value for sure. Why? it would *increase* their revenues within their marketspace. They have stores now and a dealer network(that if they don't irk off) is set up to push product.
This rumored deal would increase value, too. But, come on. The whole widget is missing some desirable pieces and Apple owned recording artists aren't really apart of the widget.
plus, that Apple Records lawsuit...Paul is Dead

, not Apple Records. They revised the terms a while back(google it). But, unless, this deal gets Paul's blessing (i.e., investments from the Cute Beatle) it seems even less likely to happen. If it does, expect MS to buy Warner Music. Which sounds even less inviting thinking that computer oriented companies own that much non-computer oriented intellectual property. nauseating, really.
hope this rumor is at best only partly true.
