I have a HP ipaq hx2490b that was given to me. It came with nothing except the unit and a car charger. It has windows 2005. The battery is shot and will not hold a charge. So, can anyone vouch for this unit and me by a battery, or should I recycle it and just find another one? And if so, what is a good PDA to go with? Something that is user friendly. As for the ballistic soft wear, what are most of you using? Nightforce, Exbal ect... I would like to be able to use and store more than one caliber. Thanks for the help in advance.
