Scott Simmons at the Pro Video Coalition was given a Dell Workstation laptop and has started a series on Editing on it after being used to Mac for years. The article is just getting started on it, but it is an interesting read and I look forward to reading more about it.
Personally I never edit on a laptop and do most of my editing on a Mac Tower (or even a QUO hackintosh at one place I work), but with the “new MacPro” (I put in quotes since it has been so long since the trashcan has been released without a single update) I have started to think that my next edit system may very well be a PC Workstation with an NVIDIA TITAN graphics card instead of the MacPro trashcan.
