I will admit to a morbid fascination for electronic to-do lists, whether on my PDAs over the years (uniformly lousy: the screen is too small, and the scrolling disheartening) or my desktop units. I speculate that it would be both depressing and ultimately freeing to see everything I have to do in one place. I've never been successful in compiling anything that seems like a complete list.
The combined to-do list for my Wonder Paralegal and me on Time Matters certainly has its utility, but I don't necessarily want to create a whole bunch of personal Matters to provide a "container" for the to-dos. Random: have picture of self taken with live python. Post to blog.
With Internet access turning up everywhere but the fillings in my back teeth these days, I've been looking at Web-based services. I started a Ta-Da List but felt it was pretty lame, although simple. Occam's Razor cut a little too close to the bone on this app for me, although I hadn't thought of putting it into an RSS feed and subscribing to it until just now (when I read it on the developer's excellent site).
Enter Backpack. Holy cow. I've yet to actually use this, but I think I could actually use the vestigal web browser on the Treo for to-dos without the entries carrying back to TM when I synchronize it with the Mothership.
A related thought prompted above by my identifying the contrast between the PDA and the hulking mothership on my desk (kind of like Baby Bear and Papa Bear). Although a laptop would be a logical place for a master electronic to-do list, I've never been a laptop girl. Either I want to carry it in my purse, or it needs to be the most powerful machine available to civilians at the time (and then I watch its power seemingly decay pursuant to Moore's Law over the next seven years because that's how long I use most machines).
Feh. I am doing more and accomplishing less.
