Smartphones are also good to put under the leg of an uneven table.
I don't want one and don't need one except to validate SMS messages when I add a new payee to my online banking. Even then I have to go outside, wait for the call, then get back to the computer in time before the pincode expires.
What you can't put in an email I don't want to hear about, ever.
