Smart home technology is becoming common enough that it's now the butt (quite literally) of Saturday Night Live jokes. Last weekend's show had a skit about a forward-thinking couple and their questionable innovations, including a toaster with eyes (googly ones for now) that can hover at eye-level and tell you how toasted your bread is and a smart couch that recognizes you by your backside. The sensor on that one is attached to a tube (also with googly eyes) that goes where the sun don't shine.

Personally, when it comes to smart technology we'd prefer this (much less invasive) tricked-out mattress cover.

All joking aside, smart home technology can make apartment-living so much more decadent. (We'd love a home that was perfectly heated and cooled at all times of the day, for one. And music piped in everywhere, at the touch of a button. And an automatic hot chocolate maker, if such a thing exists.) If you're pining for a tricked-out apartment, feast your eyes on these:

• An $8.2 million three-bedroom, three-bath Turtle Bay condo with a smart home system that manages lighting, music, and security

• A $14 million three-bed, four-bath penthouse condo with smart-home technology (and a 2,000-square-foot private terrace)

• A $13.495 million two-bedroom, two-and-a-half bath in the famed One57 building has smart technology and full Central Park views

• A $7.3 million three-bedroom, four-and-a-half-bathroom Tribeca condo that's pre-wired to accommodate smart home systems
