At first, it was troublesome for me. I was using a HP which was using Windows OS, and no questions like this were required to be asked. But then since MBP came into my life, I always had to ask. If I take softwares from friends, high chances, it is not compatible. But then, I'm learning to live with it. MBP requires special attention for a lot of things are mostly are complicated. You need to undergo a few steps to get something done, unlike in Windows only one step is required. Though complicated, I still love you MBP.
Well, one thing I don't have to ask about now is 'Does the pendrive have virus?' for MBP is said to be virus tolerant!
