=== Overview

"Mobile" -- an astoundingly popular
collection of new products? Yes.

"Changes everything"? No.

Mobile is new and popular? Yes, and at
one time in the US so were tacos.

New and popular are not nearly the same as
changing everything.

=== Use a Smartphone?

Could I use a smartphone to buy from
Amazon? Yes. Would I? Very definitely,
no!

Why not?

(1) If the user interface (UI) is a mobile
app instead of a Web page, no thanks.

Why? Because with a Web page and my Web
browser and PC, I get to keep a copy of
the relevant Web pages I used in the
shopping and buying. And I very much want
to keep that data for the future.

(2) Want to keep those copies of Web pages
on a mobile device? Not a chance.

Why? Because for such data, I want my PC
with its hardware and software. I want
the Windows file system (NTFS), my text
editor and its many macros, and my means
of finding things in the file system.

My PC also gives me a large screen, a good
keyboard, a good printer, a mouse (I don't
want to keep touching the screen -- in
fact, my PC screen is not quite close
enough for me to touch), ability to
read/write CDs and DVDs, backup to a USB
device, etc.

Do I want to backup to the cloud? Not a
chance. I backup to local devices.

Why? Because for cloud backup, money, a
cloud bureaucracy, the Internet, spooks,
and lawyers could get involved.

=== Business

My business is a Web site. I'm developing
that on my PC, and will go live on a PC --
in both cases, a PC, not a mobile device.

Mobile users of my Web site? Sure: My
Web pages should look and work fine on any
mobile device with a Web browser up to
date as of, say, 10 years ago.

=== New Business for A16Z

It sounds like A16Z likes mobile because
for 2+ billion poor people smartphones are
their first computer and are new and
popular.

Okay, then, A16Z, here's another business
you should like -- bar soap. Also, of
course, just from the OP, tooth brushes.
No way should we forget -- salt. Okay, of
course -- sugar. Sure, one more -- toilet
paper. Naw, got to have one more, plastic
knives, forks, spoons, and drinking cups.

Not to forget -- sell them batteries for
their smartphones. Maybe even solar panel
recharging for their smartphones!

Especially for A16Z, got to have one more
-- sure, Kool Aid.

=== Summary

A computer is the most important tool in
my life. Currently my PC is my computer.

A smartphone most definitely does not
replace my computer.

Actually, at present I have no use for a
smartphone, a cell phone, or a mobile
device and, so, have none.

Actually some years ago a friend gave me a
cell phone. Once I turned it on, and some
complicated dialog came up about my
reading some contract and sending money.
I turned the thing off and haven't turned
it back on since.

Or, my PC has a network effect: It has
all my data and means of entering,
storing, processing, communicating, and
viewing data, all in one place. A mobile
device cannot be that one place, and, due
to the network effect, I don't want to
split off some of my data into a mobile
silo.

=== Denouement

This post was written, spell checked, etc.
with my favorite text editor, using my
favorite spell checker, on my PC, and no
way would I have wanted to have done this
post on a smartphone.
