David: Does that mean you prefer your non TS-E lenses when it comes to landscaping? I mean since you said you mainly (mostly?) use it for architectural photos. Please elaborate on this, because I'm still trying to decide if I should buy a tilt-shift or a new UWA-zoom for my landscaping.

I've borrowed the TS-E 24 mm, and I do like it.. I'm just not sure "how much" I like it. lol.
Mike: like the others said, making miniature landscapes with the 17mm will be kinda tricky. It is not entirely impossible, but the effect will be kinda weak, compared to the 45 mm and 90 mm TS-E.
My TS-E 24 II has been my go-to landscape lens. That may change since I've just added the Zeiss 21 to my kit. I don't typically use the TS-E 17 for landscapes because it doesn't easily support filters. The new Fotodiox filter kit may be changing that situation, but it's still not as flexible as the Lee system that I use on the TS-E 24 II. When I'm seriously considering a new lens I look carefully through the images in the Lens Sample Archive and if you do that you'll see a lot more landscapes in the TS-E 24 II thread than you will in the TS-E 17.
Now I'm going to share my opinion about tilt-shifts, others will disagree, it's just the way I see things: Wide-angle tilt-shift lens are problem-solvers for architectural photography: they provide perspective correction. But, regarding landscapes, I don't see tilt-shifts solving any specific problems. Shifting isn't necessary and tilting the focal plane creates the blurring effect, which is good for a neat effect (which might result in miniaturization in the right context), but not needed, or even desired, for landscapes. So, in my opinion wide-angle tilt-shifts are architectural lenses that can also do landscapes. Switch to a Zeiss 21mm (or the new 15mm, or 2/25mm) and the situation is reversed: awesome landscape lenses that can also be used for architecture (albeit without perspective correction).
One reason the TS-E 17 might be a great landscape choice...it probably is the sharpest/finest lens in that focal length for Canon cameras. If you're looking for an ultra-wide it could be the best choice for that reason alone. The Zeiss 15mm might be sharper, but it vignettes more and costs a lot more.
And back on the subject of miniaturization, I'll make a few observations about the TS-E 45 and 90 lenses. If you look through the archive for those lenses (also take a look at image groups on Flickr) and you'll see far more full utilization of the shift movement. You'll see loads of miniaturization shots there. With the 17 and 24, the shift movement appears to be dominantly used, but with the 45 and 90 it seems the tilt movement dominates (or is at least used a lot more).
I am planning to add the Zeiss 15, and then I'll have the Zeiss 15, TS-E 17, Zeiss 21, TS-E 24, and Zeiss 35 and 100. I feel it will be a pretty complete kit for both architectural (mostly TS-E) and landscape (mostly Zeiss). Now I just need Canon to make me a 46.1 MP camera!
