Hi all, I'm thinking about getting a new Powerbook for my first Mac and had a couple questions: 1) When connecting an external display to the span the desktop, can you choose whether the ext display is to the left or right of the laptop display? Also can you choose which one is "main" display (with the dock and all)? 2) I generally keep my computers for quite a while since i don't have the funds to upgrade every couple of years like most people (i've bought new PCs every 4 years or so)... just wondering who long you would expect Apple to be producing batteries for the current powerbook? Would it be at least 4 years? Because a laptop is kinda useless if you can't get new batteries for it.
