Nothing anti-Apple in this article.
PA Semis clients won't have too much to worry about quite yet. They will still have contracts that need to be met by PA Semi. The problems may arise after those contract expire and they need newer chip designs. Apple could still allow the PA Semi boffins to create work for other organisations, but I promise you now they won't be producing chip designs for LG/Sony/Nokia etc.
I don't think anyone outside of Apples upper echelons *knows* why they took PA Semi in-house. There's a lot of talk about the next iPhone or whatever, and the aggressive powerstepping technology helps support that argument, but Apples growth area at the moment is in Macs not iPods. The low power chips give Apple the edge in portable computing and low end servers (especially home media servers which may sit idle for hours on end, then be required to serve a few songs, then encode HD TV to disc). The low heat output also gives Apple many more options regarding form factor, which is where they can stand out from the Intel boxes.
As for why PA Semi "sold out" - the economic downturn in the USA isn't good news for VCs. They'll have seen that their investment in PA Semi has almost topped out for now, and will have wanted to liquidate their holdings. Apple offered $278m in *cash*. Had the buyout been funded by stock I doubt it would have been accepted, but it's a brave man that turns down that much cash in todays economic climate.
Well regardless of whether I'm in the right ball park or way out, it'll prolly be 18months or so until we see any real results from the acquisition. I look forward to whatever cool toys Apple produce off the back of this.
PS, John Parker - 'Maybe Ben's spelling of "were" is telling as to his intelligence'. Yes, it says he can spell.
