Hey there, BlueEyes!
That sounds like a truly spendiforous treadmill, but I think you should have held out for the model that wipes your brow and hands you your water bottle from time to time.
I use a home treadmill too (although I don't think I am ready yet for one that is permanently set to San Francisco hilliness --- whew!) and it really makes a big difference for me by eliminating all the "getting to the gym" excuses. This is going to be one of the best investments you have ever made!
Congratulations on your loss so far and I look forward to hearing more about your adventures!
So, do you listen to music or watch TV or anything while you walk?
