Can't sign in to Google calendar on my Samsung refrigerator
I remember seeing a commercial for those things where they drafted the Top Chef brothers, and even in the commercial it looked extremely awkward to use.  "Oh, let's just look up something...(walk over...bend down...glance at screen...slowly punch things in...)."Even if it were the best thing ever, I know technology and I know that fridges last years longer than any gadget ever has.  Any choice of touchscreen, OS or even network connection technology would probably be a "bad idea" in 5-10 years.
