For most jobs, are there really any barriers left to using a Mac at home and PC at work? Considering computing for the vast majority of workers likely consists of email, excel, word, and powerpoint, I can't think of many. Certainly in-house apps would only work on Windows, but who uses those on their home computer?
Overwhelming user pressure is slowly bringing Macs into the workplace, but they're only feasible because something like Citrix XenApp (aka Presentation Manager aka Metaframe) servers allow access to decades of in-house Windows applications.
