It is quite difficult to use tablets, specifically Apple tablets in the field as you are not allowed to use WiFi and Bluetooth. Some Android tablets, however, have the ability to connect an ethernet cable. I believe that e-scouting is quite reserved to laptops, which have some unbeatable features:
- Ethernet Ports
- USB Ports (for PPTP over serial if necessary)
- Full desktop OS makes it easier to develop and deploy servers
