I'm looking to purchase a new laptop that will be exclusively used for writing and research (i.e. no photos, music, etc). I presently have all mac computers except for one windows. I noticed that logos runs much slower on OSX then on Win7. Is this a temporary thing as they work out the kinks? The reason I ask i'm deciding between Macbook pro 15 or Dell XPS 15. I love Mac but the XPS is almost a 1,000 less with similar if not newer components. Not to mention running logos seems faster on a windows computer... Any suggestions?
