Forgive me if this is question Im assuming you are all familiar with, but I need some direct input as sales associates at various stores are unable to help me as they don't know the products well enough. I am a long time PC user and am in the market for a new laptop. I would say my computer knowledge is perhaps novice. I have always heard macs are a great computer, but I would like to know why they're so great compared to a PC. Ultimately I will be using my laptop surfing, word processing, watching movies, downloading media, and perhaps some autocad, I don't play games. I have visted the Dell website and found their XPS 15 models, and they appear to offer 2x the computer for essentially $600-$800 less. For example: 2.2GHz Intel Quad Core, 6GB ram, 750GB Harddrive at 7200rpm, Nividia Geoforce 1GB Graphics, Blu-ray burner, JBL Speakers, 15.6" FHD B+RGLED TL 1920x1080 monitor, 2.0MP HD Cam, 9 cell battery, and microsoft office for $1568.99, OR alternatively the same model with 4gb ram, 500gb hard drive at 7200rpm, and no blu-ray for $1418.99, also possible to subtract $200 for the 2.0GHz Quadcore. Now with the macbook pro lineup of 15" models I would for sure like a hard drive working at 7200 rpm, the 1688x1050 display, and microsoft office. I need input as to why am I paying so much for the macbook pro? What makes it so much better than the machines I can get from Dell? Is it really worth the extra $600-$800? Do my computer needs justify such powerful machines? Advice/comments would be greatly appreciated.
