The fact that I use my device at work doesn't mean I have to work on it after hours. Use it for work at work and for me outside of work. This whole idea that because something is possible it is appropriate is ridiculous.

I work in IT and have no mobile phone, no tablet and no smartphone. I just can't come up with an adequate reason to buy any one of them. I neither need nor want to be available 24*7. The ability does not imply the necessity.
