For those of you Mac users, here’s a little tip I was able to take advantage of this week: Apple will gladly replace your Apple branded wireless products at no cost — and regardless of how old they are — as long as they are currently in use by a Mac that has an AppleCare plan. My five-year-old Airport Express router finally took its last breath on Friday and after a quick call to Apple’s support line I had a replacement mailed to me overnight.
