Sharing computers

Someday when I'm rich and famous (or old and lonely) I'm going to have my very own laptop and I'm not going to share. Does anyone else have these issues? Back in the old days I could write whenever the 'muse' hit me. Now, I write when my favorite teenager is working, still sleeping, or at school.

I guess I could exercise the muse with the old pen and notebook. Some tools will never go out of style.
