Never owned a Macbook before and I am planning on buying one in the next couple months. I have a couple questions that maybe someone can help me with: I have multiple gift cards. Can I use multiple gift cards online at the Apple Store? Do they expire? Also, how are Apple computers when it comes to viruses? I have gotten several different trojan viruses in the past from downloading music or clicking on something by accident on Dell laptops. Are their any programs I can buy for Apple computers that will help with getting rid of viruses? If I get a virus somehow, does the Apple Care Protection Plan cover that? Will the protection plan also cover a replacement battery if in 2 years from when I buy the Macbook the orginal battery doesn't work as good? Also, will a Logitech Wireless Mouse work on a Macbook or do I need to buy the Apple Mighty Mouse? Thanks!
