I still wonder if the fourth gen iPhone will have hotspot. If it doesn't, they'll be behind several phones on the market. Given these plans, though, I certainly wouldn't want to be sharing a 2GB bandwidth cap with 8 devices

I've used tethering on several occasions in the past with a few different phones, and I'd pick hotspot sharing over tethering any day. Even bluetooth tethering is annoying, and requires more work to connect to than a simple WiFi network.
