They are really quite convenient. As long as their batteries hold out you have time and position at your fingertips. Their only drawback is that at power-on it can take them some minutes (depends on the model) to acquire enough satellites for position fixing. But since only one satellite is needed for time, the time usually is available right away. It also helps to have most of the sky unobstructed; for satellite watching you probably have that anyway. The price for such handhelds is coming down too. Some can be had for about $200 (US).
