I imagine the ride would be less smooth...unless it's a flexible rubber. But that then brings the issue of being more susceptible to road wear and being mishapen in a time of non-use as you mentioned.
Seems much handier than trying to find a functional air compressor at a gas station or wherever. Then again, one could just carry one of those old-school hand pumps in a backpack if on a long trip.
The smoothness of the ride might be critical if on a long journey trying to GTFO of someplace. Say you have to get off the bike and run, but pain from poor ride quality impairs that...

It was 112 years ago that John Boyd Dunlop invented the first pneumatic (air-filled) bicycle tire—and a few days later, the first flat. Riders have been dealing with flats for decades, but now a California-based company, Specialized Bicycles, has applied for patents on a combination of technologies that promise flatfree riding without loss of performance.
Aimed at recreational riders and cycling enthusiasts, the new next-generation Armadillo family of road, off-road, and hybrid tires is the result of an intensive two-year collaboration between Specialized and DuPont to combine the ride and handling of the company’s premium cycling tires with an innovative three-stage flat-protection technology. Armadillo casings feature a subtread barrier of DuPont Kevlar fabric impregnated with a Kevlar-engineered elastomer that seals all gaps in the fabric weave. A synthetic cap ply material—a lightweight version of the latest off-road motorcycle racing technology—prevents sidewall cuts. The technological troika is so effective that Armadillo recently defeated all challengers in independent lab tests at the University of Nevada at Reno.
The studies were completed in June and compared various Specialized tires against offerings from other leading manufacturers in an all-too-real situation: researchers rode five different tires 12 times each through a wooden trough lined with jagged glass shards. Of the tires tested, only the Specialized Armadillo survived without a flat.
While no pneumatic tire is 100 percent flatproof, the Armadillo flat-prevention technology has proven so effective that Specialized is now offering an unconditional guarantee on all 2000 model year tires. If any Armadillo tire ever flats in use, the company will replace the tube free. Consumers can write to Specialized describing how a puncture occurred along with tire size and tube type to receive a replacement tube at no charge. The best "How I flatted an Armadillo" stories will even be posted on the company's Web site at www.specialized.com. Specialized says its no-fault replacement offer is good through Sept. 1, 2001.
