I have a iMac at home and have PC's at work. I have 2 businesses, which causes me to travel now and need a laptop. My POS/Computer tech told me that Macs are lousy for business use. In example quick books and other things like back office use for my POS register system, which I already use my PC station for that. He also told me that my DVR security camera system will not be compatible for the MBP to view remotely. This is not 100% necessary. Input please if MBP will be lousy for business use.
