When you’re running on the treadmill, it’s probably hard enough to focus already with all that sweat dripping so surfing the web sounds good in theory but probably not without its difficulties. With that said, if you want the latest and greatest of treadmill innovations, the Trailrunner 4.0 Proform is a good candidate.

The Trailrunner 2.0 is probably a better choice for those who want to be slightly more frugal as a slightly inferior motor with the web browser technology can save you.
