Hello All I am a BRAND NEW MBP user. In fact my new laptop arrives today, and it will be my first experience out of the Windows World. My new system apparently ships with Snow Leopard, but I will be allowed to upgrade to Lion for free. My question is, should I do it? I figure since I wont know any better, I might as well. even if it is different from Snow Leopard, it is bound to be better than Windows Vista, which is where I came from. I have just read some MBP users are unhappy with its performance. But being a new user, will I notice it? Or will it just be so much better than Windows I will be blissfully ignorant? I am just using this MBP for home\basic use and was just tired of Windows sluggish performance ,constant background processes, freeze ups, and security issues\maintenance. Thank you for your input!
