Greetings, I'm new to the Apple family after purchasing a new Macbook Pro 15". It's still in the box by the way with the Snow Leopard insignia. I'm an old PC guy (since the DOS days) and want to start my new learning experience with the Lion OS. I would appreciate some feedback on getting started. Here are a few questions that come to mind. 1. I know Apple is offering Lion as a free upgrade within 30 days of purchase. Would it not be best to do a clean install of Lion as opposed to upgrading from Snow Leopard? If so, I need some guidance. 2. Others have said I need to register with Apple and to obtain an Apple email address. Is this necessary? 3. As stated before, my Macbook Pro is new (still in the box). I've learned that some of the F keys have changed with Lion. Has the printing on the keys changed as well? If so, should I return the computer and exchange for the newer keyboard? I'm sure I will think of other questions later. Thanks for all of your recommendations and advice.
