I just confirmed this morning that our new Macbook (1 week old tonight) has a non-working ethernet port. We use Airport the vast majority of the time, but ethernet is sometimes needed, so this must be fixed. The question is: should I ask for a replacement (swap at the store and walk out with a new one) or should I send it in for repair (wait a week or more)? Here are the considerations: In favor of replace/swap: The up arrow key us a little mushier than all the others, requiring more force to register a keypress. Slightly annoying, and hopefully a replacement would have all keys working 100%. No waiting for repair to come back. In favor of repair: This machine doesn't seem to have significant heat issues. It gets what I would describe as very warm but not scalding hot. What if I got a replacement with a true problem? No whine with this machine. No moo with this machine. No dead pixels. Either way I'll have to backup what's important and wipe clean any personal information before going in. What would you do? Replace or repair?
