Apple Working P.A. SemiTablet? P.A. SemiPhone?

Macworld 2009 is still about a month away and already, Global Equities Research analyst Trip Chowdhry is frantically turning the hand crank on the rumor mill. In a note to clients today, Chowdhry claims Apple (AAPL) will debut an entirely new device category next year.

Sounds intriguing, yeah? So what it is it?

Chowdhry hasn’t the faintest idea. But he speculates that it will involve chips developed by P.A. Semi, the boutique semiconductor design company Apple acquired last April. A clearer picture of what’s in store for us will emerge in early 2009 with a series of new Apple patent filings says Chowdhry, who contends that a P.A. Semi chip has also been designed into the third-generation iPhone–which will boast vastly improved performance and battery life over its predecessor.
