Here is a link from another thread I thought I would share. They tested Air-Pots vs regular containers though. They should do a follow-up study with Smart Pots.

Conclusion
The results of this study suggest that the container typology has a strong influence on root system conformation in the two tested species. Plants grown in traditional smooth-sided containers showed the highest percentage of deformed roots compared with plants grown in containers with air-pruning or mechanical impediments.
