I think the "why not just get a Strom?" folks are missing the point. It assumes a motorcycle is fundamentally more capable that an equivalently priced and same-technology scooter. And in preformance that's generally true.
But in many areas, the scooter is fundamentally a more capable vehicle. It has more storage, more weather protection, and more comfort. In short, it has more utility for many applications, particularly for urban environments. They're easier to live with and use day to day.
With the gas prices staying high, we should see people start to view motorcycles as a practical solution to transportation needs, not as simply sport and recreational vehicles to have fun on. As this occurs, the scooters should be able to support higher and higher price points.
