Are smart phones for smart people?

So here I am day 2 of my "real" vacation with nobody asking me for help and I find myself checking in with my office. My recent purchase of a smart phone was for the purpose of having my schedule at my fingertips - smart right? So why am I using my smart phone for e-mail while on my real vacation-am I as smart as I think I am or is this a sickness that afflicts all business owners?
