I need a new Windows laptop for work. I have windows desktops in my office and home office, so the laptop will only be for travel. I also need a Mac personal laptop (currently have a 2011 MBA 11"). I am hoping to kill two birds with one stone by running Windows via VMWare on a new MB. I am a financial analyst. My most demanding requirement is running VBA macros in Excel. However, if VMWare is laggy on the MB, i'd rather just get a dedicated WinBook. Hoping to hear from others running MSoft apps on the MB.
