Yesterday could have gone better. My computer at work died a quick yet painful death in the middle of the afternoon. When you hear a grinding noise, followed by a "Disk Read Error, Press Ctrl-Alt-Del to Restart" on a black screen, you are SOL. Goodbye, my 2-pound Portege, you served me well for the past 8 months.
Fortunately, the guys in IT may be able to recover some of my files, and all the important web files are on the server, so the Web site is safe. My email is on Outlook, so i only lost older files that I wasn't ever going to look at again. They had extra laptops, so in truth I was without a working computer for a total of 90 minutes, and for half of that I was in a meeting, anyway.
My programs, utilities, settings and other files, unfortunately, have perished.
All my bookmarks are stored in del.icio.us, so I didn't lose those. That would have been a tragedy.
I was able to reconstruct most of the programs and utilities I use in about an hour, but itmay be weeks before I get back to where I was just 24 hours ago.
Here's my list of essential (and non-essential) tools for doing my job and otherwise getting through the day.
Dreamweaver (I ordered Studio 8, but it's MX for now)
Adobe Photoshop 7
Adobe Acrobat
Firefox and related extensions, mainly the developer's toolbar
WinSCP
Textpad
Winamp and Streamripper
Google Toolbar
Adaware
Spybot
SmartFTP
Freemonitor for Google
Trillian

This will be useful for the next time a computer around me dies.

The moral of this story: back up your data often.
