Tonight my PowerBook G4 suffered a kernel panic on startup, which I determined was caused by the failure of the lower memory socket. I removed the memory from that socket, and now all is well (albeit with less RAM than before). I was planning on using this laptop until the new MacBooks come out, whenever that may be. My question is whether I should take my chances with one good memory socket, or should I just go buy a MacBook now. I have no idea how likely it is that the second socket will fail. I'm in my first week of law school and I'm pretty reliant on my laptop, if that makes a difference.
