Our wireless at work has a mac table setup with unique keys so anytime someone forgets/otherwise screws up their wifi connection they come to have it reset... Everytime I make a comment about how they are really only draining their battery by leaving wifi enabled 24/7 yet they continue to do it.. SO - what do you use WiFi for? I know there are some (very, very few) apps that require a wifi connection.. Facetime requires WiFi but at this point it's more of a novelty than anything else.. Throughput is a little better but not enough to justify the additional battery drain.. The hotspot app (as soon as the IP4 jailbreak is released..) Checking mail/browsing the net in an area with no at&t service.. That is all that comes to mind.. I think they just like to enable it because they can, but let me know if I'm missing anything?
