If you use a smart phone or work between different desktops and laptops, you simply must look at Evernote. Highly recommend. I found it on the iPhone and I use it to sync between windows, mac and the iPhone.
I use it to capture great articles I find, save important emails I want to remember for a long time, keep stories that people pass along (which I mentioned earlier) and generally use it as a repository for lots of things.
Ok, this was a commercial, but it was for a great product.
