way to miss the point there buddy.

the title is
9 Things You Would Immediately Fail Without Your Smartphone.

im sorry but if i lost my cellphone today, i just proved i wouldnt fail at these 9 things. nor do i think half the population would either. unless ofcoz people are addicted to their phones in which case they have issues.

Yes, you will fail at some of these things if not all of them. Nobody carries a pocket mirror, Map, Calculator, etc nowadays so Yes, you will fail at these unless you're already prepared.
Also, I don't think everybody has the same level of genius as you to remember many phone numbers, why would I remember numbers if a smartphone can do it for me, if it goes missing one morning I'll fail at that too.

"Yes, you will fail at some of these things if not all of them. Nobody carries a pocket mirror, Map, Calculator, etc nowadays so Yes, you will fail at these unless you're already prepared. "

You're assuming people are too stupid to do very simple things.

Mirror? My car has several, I could just use one of those. Almost, if not all public bathrooms have a mirror in them. If you needed to use a mirror, you could easily figure out a solution if need be.

Map? Unless you're somewhere you've never been before, you shouldn't need directions to your house. If you're going to a place that you've never been before, you could easily buy a map or ask for directions.

Calculator? Figuring out 15% is actually pretty easy. Lets say your bill is 56.49. You could just round that down to $56 even or up to $57 and then figure out 10%, which is obviously $5.60 or $5.70. Divide that by half to make $2.80 or $2.85 and then finally add the sums together to make $8.40 or $8.55. This isn't far off the actual total, which is 8.4735. So you would either be 7.357 cents short or over by almost 8 cents, which means absolutely nothing to anyone. If you don't want to be "rude", you could always round up so you know they're always making at least (obviously over) 15% per transaction.

The same can be said about a lot of these things. You don't actually need your smartphone to do a lot of these things, but you could easily do them, if you absolutely had to, without the need of a smart phone. Just relies on how resourceful you're.
