To me, 4x5 and other LF cameras are more about tonal scale and less about movements.
The Travelwide with a Schneider Angulon 90mm lens essentially gives you the same field of view as a 12mm lens on a FourThirds format sensor, a 50mm lens on 6x7 film, a 21mm lens on FF (film or digital) cropped to 24x30mm, etc. The differences between these different formats with equivalent FoV—aside from the workflow differences between film and digital capture—all have to do with how they produce different levels of depth of field control (since you don't have shift and tilt controls).
The nice thing about shooting 4x5 with B&W negative film is that you can contact print it to stunning quality positives that are a useful size just as they go, or scan it to huge, high pixel count digital files with enormous tonal differentiation and detailing.
The Travelwide with a 90mm lens reminds me of my last 4x5 film experience. My friend built the equivalent of the Travelwide more than 25 years ago in wood and loaned it to me for a while. It was a purpose-built wide 4x5 camera, just like the Travelwide, and proved just as nice to travel with (albeit a bit heavier), and it made stunningly nice negatives when used sensibly–as it was intended to be, that means. It was not a general purpose camera, but I bent it to use doing street photography, fine art geometric abstractions, and even some environmental portraiture.
At about $150 plus the cost of your choice of lens, to me this is a pretty cheap way to work with an interesting, single-purpose camera and make some fine photographs. Any of the lenses mentioned above would cost more, never mind the camera they're attached to.
What it's not is an introduction to large format photography, either with a field camera or a full studio camera. The lack of shifts, swings, and tilts precludes much of what most people think of when they think of large format photography. If that's what you're after, this is the wrong camera.
My point of view: Creativity blossoms in constraint. If I were interested in working with something in 4x5 film, I'd order a Travelwide tomorrow. In fact, I'm working on building something similar using Instax Square film and a 40mm lens/shutter from a 35mm folding camera. Should be a hoot if I ever get it done. 😀
