This week I have found an article that explains the difference between Ellipticals and Arc Trainers. They are a pair of similar machines and i think it could be helpful if you are in the market for one to know the difference between the two. This is from Livestrong.com:
Overview
Arc trainers and elliptical machines are similar pieces of equipment that can burn calories. Both of these cardio devices help eliminate stress on the joints that is associated with running. The main difference in these two fitness machines is that an arc trainer's foot plates move in a different path than an elliptical machine's.
Arc Trainer
An arc trainer is a stationary, low-impact machine with adjustable incline and resistance settings. According to Dr. Paul Juris of Cybex International, which developed the first arc trainer, the difference between the machine and an elliptical is that the arc trainer's footplates move in an arc pattern. An elliptical machine's foot plates rotate in an ellipse pattern. The idea behind the arc pattern is that the movement is comparable with the elliptical's but requires less movement. This allows for less stress in the knees and hips, while increasing cardiovascular endurance.
Features
An arc trainer is equipped with a manual workout option that allows users to exercise at their own pace. The machine has pre-set routines for "hill" workouts, as well as low- and high-intensity intervals, weight loss, cardio and increased resistance options for strength routines. The machine also has a heart-rate monitor, and calorie counter and displays the distance traveled on the monitor screen. The flywheel that drives the resistance is in the front of the machine.
Two types of arc trainers available. The lower-body version has handlebars on the side to hold onto, but doesn't have moving hand poles. The total-body version has moving hand poles. This allows for lower-body and upper-body resistance during the workout. The poles move in the same motion as their respective foot plates, so if the left pedal moves forward, the left pole will move forward, too.

Elliptical Machine
The elliptical machine also offers a low-impact cardiovascular workout. The pedals rotate in an ellipse pattern. The pedals activate the flywheel that creates resistance for the user. Some elliptical machines have poles that allow the user to work the upper body as well. The overall movement of the elliptical is a combination of cross-country skiing and stair climbing.
Proper posture and form are necessary on the elliptical. According to Dr. Edward Laskowski of the Mayo Clinic, it is important to keep an upright posture and allow your lower body to support your weight. This will also help keep your feet in contact with the pedals.

Features
Elliptical machines have manual programs and a variety of interval settings that allow the user to exercise at several intensity levels. On some models, you can also adjust the incline level, resistance and stride length for a more customized workout. Heart rate monitors on the handles and distance and calorie meters are standard on commercial health-club ellipticals. Some ellipticals have moving hand poles for upper body resistance, while others have only hand rails. Most elliptical foot pedals can be driven in both forward and reverse directions.
