The one problem that you run into is that a lot of theaters use Digital IMAX, which has been given the cutesy name "LieMAX" since it isn't true IMAX resolution. You can read more about that here: http://www.slashfilm.com/qa-imax-theatre-real-imax-liemax/

I've been well aware of the difference in Digital IMAX and the actual 70mm IMAX film format - problem is, it is exceptionally rare to see 70mm IMAX auditoriums. Most of them, if not all of them, are stand-alone auditoriums or otherwise purpose-built.
Also, the issue with the actual screen size is not always the case. I too have a theater or two around here, where, at least two of the individual auditoriums have absolutely massive screens that are in fact larger than some of the smaller Digital IMAX screens.
The thing is - I don't see a need to be offended or anything by the smaller Digital IMAX screens, as the main purpose is still fulfilled - it's a better audio and visual experience. Sure, it may not be an 8-story screen, but it has superior resolution to the digital projectors used in standard theaters.
Those Christie projectors are beautiful.
Now, the other thing: we should all be offended by resolution, in general. 35mm film has superior "resolution" to that of the digital IMAX systems. More importantly, 35mm film (specifically in vertical video format, where the image is even smaller) blows away the digital projection used in standard theaters.
Film has no resolution - what it has is purity and beauty that can be enlarged far more than a 2K or 4K digital image, regardless of the level of image compression. So our digital theaters have a LONG way to go before they can truly deliver the epic imagery previously found on film. If they start with 70mm IMAX film and still show it in a Digital IMAX theater, it does have such a higher -quality starting point that no other digital theater will be able to come close, because the digital source file will have superior detail as a high-bitrate starting point, so it will be that much cleaner when they create the final video format for digital projection.
It's also not all about the actual image resolution from the projector - there are specific Hollywood standards (that all studios agree to for universal distribution... for the most part) that dictate the final digital compression type, the actual video resolution and the total bitrate, and of course the final container format. Same goes for audio.
Just as the standard digital theater (35mm replacement) has a set of standards, the files and equipment for Digital IMAX have a set of standards too. The video file will have a much higher bitrate, and the final resolution is higher as well.
I'm sure IMAX will actually encourage adoption of a new system with higher resolution in a few years, as the digital theaters will be upgrading to equipment that should be able to match it at some point in time.
Even for IMAX, the 70mm format is a dying breed when it comes to true projection. It'll be used for filming for some time, I'm sure, especially by the film-loving directors of the world (a dying breed as well 
), but as that site noted, there are less than 50 IMAX theaters that use 15p70mm AND show Hollywood productions. There are the domes and science-theater ones that will show various IMAX Experience events, but not Hollywood films, so we might as well ignore those, as Hollywood is the point of this thread.
Apparently there is one or two in Detroit, I think three if you count a dome, I had been to either the dome or the one at the museum, and I suspect both of those do not show Hollywood films. The other one sounds like it may be a proper Hollywood theater - and as suspected, the closest one in Ann Arbor appears to be digital. It is within a multiplex, I'm pretty sure it's a digital retrofit.
edit:
I lied. In the Detroit/Dearborn region, there are two 15/70 theaters, one is a dome, and both are non-Hollywood. All other IMAX in the region are fully digital. Well, one in Grand Rapids appears to have both 15/70 and Digital.
This blows. Why does the world hate Ohio and Michigan? Hmm? We give you so much, and you give us no beautiful film in return. Bunch of haters.
