For those that like to play with numbers, below are quarterly sales data for iPhones and iPods. Since I like to get a new gadget every couple years, if we only consider sales data for 2009 and the 2010 (to date)... there have been ~38 Million iPhones and ~86 Million iPods sold over the last year and a half.
Even if only 1 in 100 people are green/energy conscious minded folks (think of your typical Apple customer :) interested in a solar recharger for their electronic devices, that is a very large number of potential customers!
Furthermore, referencing today's PR: I'm not even going to try to count the "other small electronic devices" that the Kenergy Solar Recharger will be compatible with, or the potential for the "three other existing solar chargeable products" that will be launching at the same time.
And this is just the first product line to be launched. I can't wait to see what else Ken has up his sleeve for SSWC!!
