PJB, my computer tasks fall into three contexts:

Macintosh: things I can do on my Mac, regardless of place/time
Macintosh:Online things I can only do online
Macintosh Offline things I can do offline, redundant with the first, I just realized.

I do have times when I have my laptop but no internet connection, so the distinction is useful to me.

Other subcontexts are (for me) just silly.
