Paper notes using any type of paper or notebook with any pen - I'm not picky. A computer has too many distractions if I get bored.
The one thing I don't like about using notepads is the the next page has the imprint of what you just wrote, so I will cut a plastic folder to the size of my notebook and tuck it in between the page I am writing on and the rest of the notebook. If the notes are 'keep' notes then I will write on one side of the page, if the notes are temporary then I will write on both sides of the page.
I might transfer my notes over to Ubernote online, but mainly the notes were to get the data so I could go get more information later or put it on my to do list.
I'm trying to get away from having everything physically on my computer as if it crashes, everything is gone, so I started to use these online tools: Ubernote for webclippings and notes, Worflowly for my home lists (shopping lists), toodledo for my work to do lists, Pinboard for bookmarks, Google Doc for the bigger documents and my yahoo/google mail for capturing misc information. I was using TreePad as my information depot but like Ubernote for the ability to multi-tag information and have it available anywhere.
When someone at work gives me a to do, I tell them to email it to me, then I will either write it down in my 'to do' steno notebook or email it to my toodledo account.
