Re: what palm to use for LR shooting
Just about any Palm will run the NightForce software, which by the way, is the same software as Exbal. You can get either software package in Palm or PPC/Windows based applications.
I use a Palm Zire for Exbal as well as a Dell Axim x30 for Loadbase. Just note that some of the lower priced Palms will lose the data and software if you allow the battery to go completely dead. There are models of Palms that don't do this.
Probably the cheapest place to get a Palm or PPC is on Ebay.
