The gym I recently joined just upgraded all their treadmills to the Precor C966i Experience. It's a great improvement over the old treadmills, especially with the additional custom routines you can program and a wider selection of predefined routines. My one big complaint is the gym went with the TV screen attached to the console (see picture). Keep in mind there are already TVs hanging from the ceiling all over the place, so these are a tad redundant. My problem is that when I don't want to watch the TV, I still have this screen two feet in front of my face. If you want to know what it is like, try running with someone else's hand directly in front of you. Lest I become a Luddite, I turned on the TV to see if I liked it. It was okay when I was walking on the treadmill, but when I started running the screen obviously does not move with my bouncing up and down, so focusing my eyes on the screen was impossible and I soon had the feeling of motion sickness (which I'm not normally prone to). So I have to give the TV screen a big thumbs down.
(Bias Disclosure: I have an aversion to TVs when running. They cut against what, for me, is a quiet, reflective moment of the day. More on that later...)
