absolute necessity

Note to Self:

You just wrote your principal explaining why a MacBook is not an absolute necessity.  You gave, as your reason, the fact that you own your own laptop running on Linux.  Here's the deal: you've gone from liking computers to needing computers to claiming they are absolute necessities.  You can live without a laptop.  (You've gone this far without owning a cell phone).  Absolute necessities are things like food and water and love and coffee.

Sincerely:
John
