It will be cheaper to manufacture and may use slightly less power but that is about it. 2) System Profiler tells me that I have 2 sticks of 2-5-3-3-0 RAM in my PowerBook.

Click to expand... Yep the last bit is the timing. The first number is the most important one. So you have what is commonly called CL-3 RAM (mine seems to be CL2.5).
