If you value this feature, we would recommend purchasing a Pocket PC device due to their higher resolution color screens. The jury is still out regarding which operating system is best. Palm's operating system is by far the most popular, due to its great speed and reliability. However, Microsoft vows that the recent redesign of its Pocket PC operating system will give the Palm OS a run for its money. At this point in time, either operating system will work fine, though more medical software applications currently exist for the Palm OS devices.
Size There are many different sized PDAs available.
In our opinion, a healthcare professional will not be happy with a large PDA, because they are heavy and difficult to carry with you throughout the day. For this reason, we like the Palm Vx's small size - this Palm handheld fits into your pocket unobtrusively and won't weigh you down. If your eyesight is poor, however, take a careful look at other devices with larger screens - you may not be able to read the Palm's small typeface. In general Pocket PC devices contain larger screens but are also heavier. Battery replacement is annoying and expensive, so it pays to carefully consider how much maintenance you are willing to perform.
