I have a Mac Book Pro with a 15" screen and absolutely love it! I was an avid PC user and always had a lot of problems, I went through 4 computers in 5 years, with harddrive crashing, viruses etc. (granted the viruses were happenign because I was in college and it happened throughout the whole school but still.) Now that I have to use a PC again at work I'm so happy I have my macbook pro at home so much less frustrating
With that said my sister has a Dell 17" laptop that she got 2 years ago and she's never had a problem and she loves it except that its pretty big and tough to carry around. She's a real estate agent and has to take it in and out of the office a couple times aday. But I think you'll be happy with waht you ordered
