Baby Monitor Suggestions?

Evita
Who loves their baby monitor and why? Have also had some mom's suggest a non-traditional monitor like the Nest and using your smart phone to view baby. 
Additionally, how do you attach the monitor in your nursery to get the best angle of baby?
I ordered the Nanit while I was pregnant, and after waiting for it for months I didn't like it! For such a beautiful camera, it has some weird design quirks that just didn't work for us.
