Never an issue. After 6 years with a 17" Mac Book Pro, bought a new 15" Mac Book pro laptop last year, no more dvr and battery life now at about 8 hrs!! NEVER had a virus and customer service is great. Remember, you get what you pay for. You want CHEAP?? You can find it but try waiting on phone for hrs waiting for SUPPORT. We now have an Ipad, Mac desktop & the Laptop. Our phones expire in October and will then get Iphones. We are VERY HAPPY with the "I" product lines!!!
