I find I do two weekly reviews: one at my office, and one at home. I do them on Fridays.
This is because my mail, files, and items I need for my home projects are...surprise! at home, and all my office files are at work. I do have a centralized calendar and contact list that merge the two, but other than that, work and home stay separate.
David doesn't really mention doing two weekly reviews, unless I missed it. How on earth would someone merge these into one review, unless they worked at home? Are there advantages to doing one instead of two?
I don't know that I want to merge them, as this seems to work well, but I'm wondering what others are doing.
