One of the advantages I see in Jay is that he has a youthful, light and sober presentation. Carrying this type of garment that can be used to be communicated is really thinking about the future. I believe that this is one of the premises that any invention must have in our time: practicality! Don't have to carry several devices so that each one does a different thing, but to have one that does everything. With Jay we are in that line. Thank you for sharing that discovery!
