I travel for work maybe eight times a year. Not constantly, but enough that I know the hotel-room-the-night-before feeling — lying there trying to think through something complicated with nothing but a notepad that's too small and paper that tears if you press too hard.
My first instinct is always to open the laptop. My second instinct is to open the laptop and immediately get distracted. Neither works. What I actually want is my whiteboard.
The Nu Board is what I carry now instead of hoping the hotel has a conference room I can sneak into.
It's an A4-sized notebook with four pages of dry-erase film. Each page has a grid-paper backing that shows through the film — enough structure to draw to scale without being constrained by lines. It comes with a small marker clipped to the cover, and you erase with a dry cloth or, more often, your sleeve.
The writing experience is close to a wall-mounted board. Not identical — the surface has a very slight texture that good glass boards don't have — but close enough that you stop noticing after a few minutes and just think. That's the test I use for any tool. If you're still thinking about the tool, it hasn't worked yet.
What I didn't anticipate is how useful it is in the kinds of meetings where you can't commandeer the room's board. A working session with two or three people around a table. A coffee shop conversation that's turned technical. You set the Nu Board between you — it's about the size of an open laptop — and suddenly there's a shared surface. People reach for the marker without being asked. That's the behavior that's hard to manufacture digitally. Collaborative tools require setup and permission; a marker sitting there just invites.
I've been carrying it for eight months. The pages are still clean. I've gone through about four markers in that time — the included one dried out by week three, which is the one real criticism I have. Standard Expo fine-tips fit the holder on the cover if you care enough to track one down.
The grid backing is a detail I've come to rely on more than I expected. When I'm sketching a system architecture or a rough timeline, having implicit scale on the page makes the drawing more honest. Things that don't fit in the space they're supposed to fit in stay too small to lie about.
Four pages sounds limiting. It isn't. I've never needed more than two in one session. The constraint forces you to erase, which forces you to decide what mattered, which is the point of the whole exercise. By the time I'm getting on the plane home I usually have one page still in use and three clean ones. The session compressed the thinking into the space it actually needed.
It's not a replacement for a wall board. Nothing portable is. But it's the closest I've found to bringing the thinking tool with you when the wall isn't an option. It lives in my bag next to my laptop now. I don't notice the weight, which is the other test I use.
