It wasn't coding, but tech support...I was on vacation from my law office IT job. All I had was my PalmPilot, the clip-on modem, and my sister's landline phone system. I spent 2-3 hours one day exchanging email with my firm's law librarian (the only other semi-technical person in the firm) troubleshooting some odd network problem. We got it done, but it was torture, tapping out messages with the Palm's stylus.
