I didn't want to post this in the mod forum since I'm not sure, but can iBook G4's (latest Rev, 14.1", 1.42 GHz) have their displays upgraded?
I recently got one for a mere $250 with a broken display. It obviously needs replacing, but I simply cannot stand the lackluster 1024x768 resolution. I found a couple SXGA+ at 1400x1050 for pretty cheap, same size, though I am not sure if the iBook would recognize the screen (due to the GPU) or even connect (if it uses a different type of connector).
Those problems would require me to swap out a ton of the innards of the iBook, which I don't really want to do. I don't doubt its possibility, and if it is incompatible, I'm not above stripping a CD mini and seeing if I can put its guts into the iBook.
I'm going to try to research this more, but if anyone knows anything about the connectors, I'd appreciate the info.
