I've had this program for awhile now but I'm just discovering how useful it can be for organizing a trip. It allows you to make notes out of almost anything (web pages, emails, pdfs, photos even videos). You can then tag them and sync it to your mobile devices and other computers.
I've got reservation emails, NY times articles, scanned pages from travel guides, etc all sync'd to my iphone and it allows me to sync my desktop to my netbook.
It's free to download and you can sync up to 40 MBs/month for free. I don't have any affiliation with them just a happy user.
