I'm on my way to becoming totally paperless. Tablet-love will do that, as the more you use the tablet feature (as I am now, even though my scrawl is being converted to text, I'm inking it), well, the more you use your tablet.
Point in case -- the other day I was planning a short writing vacation. A train trip where I'd ride the train to Seattle (writing all the way), spend a day sight-seeing and hanging out in cafes, then spend a day in the rainforest doing research for my novel, then back on the train to write some more.
In the past, I would have inelegantly scrawled my planning notes on the back of an envelope. Not anymore. tablet PC to the rescue:
Okay it looks about like the back of that envelope! The major difference? Aside from the obvious paper savings, I won't lose these notes 12 minutes after I take them. And they're searchable! And I can easily erase, copy, paste, and post them to the Web. Gotta love it!
