There's still a huge untapped market for apps and hardware for the elderly. Last year I did a marketing project, and got some fairly nice insights. For example, most people between 60 and 75 in developed countries don't consider themselves "old" and are mostly self-reliant “Seniors do not think about their age in general. Unless extremely tired or depressed, older people do not think of themselves as old. Advertising that talks to the silver citizen’s active lifestyle rather than to or about his age are preferred” (www.brandchannel.com). People in that age range now desire several of the same products as younger people, like iPads or iPhones and Kindles. Our specific product failed in the customer validation stage, but there's a huge untapped market out there. Heck, I've almost talked myself into trying again :)
