A way to remember things
I've been thinking for a while that I need a way to note things down to think about later. Like, I might hear a song in a café and want to Google the lyrics later on. Or I might want to remember an event, or that I need to do something for someone.
I carry a cellphone and a digital camera with me all the time... so perhaps I could send myself an e-mail from the cellphone and put the reminder into my Topic Exchange to-do list. Or I could take a picture of the thing to remember, if it's something I can take a picture of.
Then I had a great idea ... why not carry around a pencil and some paper ...
...
The scary thing is that it took me several months to figure this out.
