I use one with an extra wifi card as a wireless router. I'm living in hotels a lot and sometimes I find their wifi too restrictive. The built-in wifi card connects to the hotel wifi and the external wifi card acts as an access point to which all my other devices connect to. This way I only need to pass the captive portal once (and only pay for one device ...) and I can enable a VPN to my home router in case I want to use Netflix or Amazon Prime in a foreign country. Another raspberry pi I turned into a listening device to analyze and modify traffic. I call it Lauschgerät: https://github.com/SySS-Research/Lauschgeraet https://github.com/SySS-Research/Lauschgeraet
