Re: yeah, right
Yeah, works great until you are somewhere without cell service service and need to consult your email. I had this happen when I was underground on the metro (subway/tube for you Americans/brits) and needed to find the email that told me what stop I needed to get off of.
Are you a member of the goldfish tribe (a.k.a. the new generation)? You know, those with the attention span of less than 5 seconds? How on Earth you boarded the tube without knowing where you'd get off?
