Is it really? Don't you get sick of being "always on" sometimes?
Perhaps the averse reactions here have something to do with too many of us living in densely populated/over-populated or even over-stimulated environments; the short-attention-span generation?
Sure, but it doesn't mean I'm without a network connection. There is no situation that I'd want to be uncontactable by everyone. I've an IM client on my phone that a very few people know the account, that will always notify, even if I've chosen to ignore every other kind of message.
