I perhaps learned the hard way in capturing new information when I took out my iPod Touch to get into the OmniFocus app to jot down incoming information...at meetings, class sessions and just hanging out with friends.

A received a few disgusted looks when I took out my iPod Touch to jot down future appointment dates and important information. I explained in a meeting of the OF App and they retreated their reservations, but only a bit.

I live within OmniFocus on both my Mac & iPod yet have noticed the looks I get when I'll take it out mid-conversation to jot down an important note the other person has mentioned. & on a personal note dont enjoy taking random quick notes on it, seeing as I have to slide to unlock, enter password, enter OF app, wait 5 for seconds for it to load, enter the inbox, add new note and then type.

You've seen those composition notebooks? Like these:

Well i'm sure you've seen the pocket size ones, like a 2 pack for under a buck. Something like this is preferable to me, however admittedly can be kinda bulky at times; similar to carrying another phone or..ipod touch.

Nevertheless am wondering what your quintissential capture tool is that you carry around everywhere? You must have one.
