August Smart Lock: Device fits over deadbolt and is unlocked via signal from smartphone. Method of letting in someone to your house when you're not there without giving out key. Or letting yourself in when you can't find your own key.
The iPhone Cordless Handset - Hammacher Schlemmer. Love the versatility of this since I can control my phone from the handset and still have it charging if I need to walk away from it! Great for home office that uses their cellphone for business line!
