Is there a strong need for these devices?Will they be affordable?It is worth considering that:
-Asthma is most prevalent in the wealthier countries.
-large increases in Asthma and lung related diseases worldwide.
-most people are not proactive in regards to their health management:they visit Hospitals.[public awareness needs to be cultivated.]
-people,especially young ones,love gadgets;also self-management has to be easy!
-KSX products don't threaten pharmacology et al.
-Governments,with debt problems,will want to outsource asthma treatment:emergency departments are getting busier.

Good Luck holders.
