In addition, the pen mouse can switch between different positions, so overuse and fatigue are prevented. What are the main advantages of the pen mouse over the traditional mouse? Its ergonomic-wise shape makes the device perfect for those, who suffer from wrist pain or carpal tunnel syndrome.Ī stylus mouse puts your hand, arm, and wrist in a position that is more natural than with the traditional mouse. But still, the main difference between a regular and a pen mouse is the shape. Sometimes, especially if you are not used to the new device, it may affect your productivity. It happens because of the size and position of the button. Nevertheless, often right-clicking with a regular mouse turns out to be faster and more accurate. They both can drag and drop, have a good point, and left-click accuracy.

The little pocket mouse is common within most of its range although it is scarce in Baja California. It forages for seeds, plant material and small invertebrates which it carries back to its burrow in its cheek pouches. It sleeps in winter and is only active between April and November with numbers building up rapidly in the spring, peaking in June and July. It is nocturnal and has a short period of activity for the first two hours after sunset, and then sporadic activity through the rest of the night. This small mouse, with a long tail, inhabits arid and semiarid habitats with grasses, sagebrush and other scrubby vegetation. Six other little pocket mice were sent into orbit with Skylab 3 in July 1973, though these animals died only 30 hours into the mission due to a power failure. It is a common species and faces no particular threats and the IUCN has listed it as being of " least concern".įive mice of this species travelled to and orbited the Moon 75 times in an experiment on board the Apollo 17 command module in December 1972. Its natural habitat is subtropical or tropical dry lowland grassland. It is found in Baja California and Sonora in Mexico and in Arizona, California, Idaho, Nevada, Oregon and Utah in the United States. The little pocket mouse ( Perognathus longimembris) is a species of rodent in the family Heteromyidae.
