What is the difference between T, E & P series Intel processor

Question

I am looking at buying a new laptop and there seems to be a whole lot of processors to choose from. I am highly confused with the Core 2 Duo's with the T, P & E series processors. Can someone please shed some light on the differences between them?

Many Thanks

E = Desktop.

T = Laptop.

P = Newer Laptop... (However some of the high end T series are better than the lower P ones).
