Apple's plastic laptops (iBooks and plastic MacBooks) have always had better Wi-Fi reception than Apple's aluminum laptops (PowerBooks and MacBook Pros). This is a well known fact, and has been written about numerous times by people who have performed side-by-side comparisons. My question is this: Which has better Wi-Fi reception: The plastic MacBooks or the new aluminum MacBooks? The reason I ask is because I am considering getting either a new black plastic MacBook or a new aluminum MacBook. Price is not an issue for me, but Wi-Fi signal strength definitely is. Thanks for any help.
