Perhaps the reason I don't mind a mix of digital and analog devices is because my apartment falls into the realm of what some may call "tech-hodgepodge" (hey, I like it that way, okay?). I feel that an all-or-nothing schema is a little bit of overkill. Time is time, is it not?
Then again, after spending some time hanging out in my friend's 'ultra-contemporary' home in Lower Highlands in Denver, it may make sense to go all-digital to keep things consistent with the clean lines and general feeling of thoughtful future eco-friendliness.
Aesthetic preferences aside, do you find it important to keep a consistent look throughout the home when it comes to time-telling?
