Greeting friends: I am a PC user of the last 20 years. I cannot begin to tell you how tired I am of locking up, viruses, ad-ware, and a slow system. I have been reviewing the MacBook Pro. I was ready to purchase a new Dell XPS 1530 and I cannot believe how cheap this notebook looks. I need some honest insight. I use my notebook daily! I am working on my MBA and spend most of the time on the web and using MS Office app's. I am now dabbling in multimedia video and audio. I have diabetes and need a screen with excellent text clarity. I have heard rumors that MACs lock up and you cannot shut them off??? I have heard that the batteries must be taken out in order to make them shut down??? You know those MAC vrs. PC rumors...I have a two year old Dell desktop which I will keeping for a while -- so here are my questions? Based on my heavy MS office use is th MacBook pro for me? Will my PC and MAC be able to communicate? (i.e. are word documents given a .doc extension? Will it easily pick up my home network? Help! I am so frightened to take the plunge!
