After using a lot of different journals, we decided to create the one that we wanted to use. 52 pages thin, matte red flexible cover, with 1/8" grid on every page. It's light weight, easy to pack, and has just enough pages to record all those crazy ideas. Also, we've altered the pages slightly, the grid is now white on grey.
These really are great notebooks, we use them constantly at the office. They're flexible enough to stuff in your backpack but rigid enough not to get torn apart in travel.
If you're more into showing off, the SparkFun Red allows you to stand out in a crowd. And anyone that knows 'geek' will recognize the subtle embossed SparkFun logo.

I am always writing things down (sometimes waking in the middle of the night to do so). And unlocking the phone, opening an app and thumbing the information in can be a chore--and doesn't feel right, plus sketching on a 5" screen isn't so great--so I keep half a dozen notebooks in continual use; this one is now my favorite.
PROs: I love the white grid on gray pages and the tight 1/8" pattern--genius. It is thin and lightweight. The bloody thing is SparkFun Red! (they have a black one too if that's your thing) The pages are numbered--cool if you want to scribble a table of contents on the inside front cover. It's nice enough that its... nice... but not so nice that you'll grieve spilling your [favorite beverage here] on the cover.
CONs: The binding doesn't lay flat. Metric would be cool.
I love the grid lines and the paper quality. We use these for our students as engineering notebooks.
