Actually, if a tech device is discontinued the price usually will GO UP. A good example are the Logitech Z-5500 speakers. When I bought mine new I think I paid like about $185 then shortly afterwards Logitech discontinued them... but I've seen prices on Amazon listed at over $1000 at times.
I've seen the XPS 12 Refurbished or used for $450-550 on Amazon and Newegg Marketplace sellers.
