For the geeks out there, having a biometric lock for your front door is probably high on your wish list. Besides the cool (ok, ok... geek) factor, its actually quite functional too. I can readily identify three group of consumers who will be interested.
(1) the ladies who loath searching their handbags for the keys. (how many times have your wife asked you to lock/unlock the door cuz its "easier" to get the keys from your pocket?) x2 for those who have to juggle the handbag with a bunch of shopping bags. x10 for those who have to juggle the handbag with a bunch of shopping bags AND an umbrella. x100 for those who have to juggle the handbag with a bunch of shopping bags AND an umbrella AND its raining.
(2) household with kids and/or old folks. Imagine no more worries about your kids and/or old folks forgetting to bring the house keys or worse, lose them when they are out!
(3) for those living in condos, how many times have you wished that you don't have to carry your keys with you when you go down to the pool/sauna/gym?
Hmm... since I fit into all three categories (Yikes!), I think I will probably get one for my new house... *grin*
