I have it on my phone, and my laptop is never far away, lol. But I'm actually a lot better than I used to be. I live a high-functioning life and only surf during intermittent down times. Emails, facebook alerts, my space alerts, do come right to my phone, though, so I am easily distracted at times.
The other downside is that I am instantly accessible by any and every one who has email or a phone... it's good most of the time, but people come to expect it.
