Very good question! :-) You can use your mobile as a Wifi-to-USB dongle and dont have to care about wireless credentials which is very nice. This is not possible with a wifi hotspot because in Hotspot mode you cannot use your wifi in parallel. I do use that with a mobile router that supports Android's usb-cdc-ethernet adapter to forward hotel wifis when i only have one code for a single device (mac address). Or when the wifi gadget you want to use doesnt work with the captive portal. Fast and hassle free.
