I'm relatively new to long range precision shooting. I want to find out what type of hardware (PDA, smart phone, tablet, etc) will run good ballistic software. I've read a lot on this forum about software, but am not clear on which hardware is required for specific software. For wxample, if a s/w program requires Android, will it run on the highly customized version of Android used by the Kindle Fire? Any help would be appreciated. I am also on a budget, so I am likely initially to select something like Shooter to get started. Thanks.
