The story goes that a decade or so ago, Apple was a mess. The
media routinely attached the adjective "beleaguered" to the company
name. Apple was bleeding market share, losing sales to PCs running
Windows - and even to Apple-licensed Mac clones.
The company's product line was littered with models with obscure
names and numbers, confusing potential consumers. Each seemed to be
on the market for only a few months, replaced by another with a
slightly different name and number.
Take the Quadra 630 series -
according to the very useful free Mactracker software, a database of
Mac models, this was the first Mac to adopt the PC-style IDE bus
for its internal drives when it was released in June 1994.
The 68040-powered Quadra 630 was also sold (with different
software bundles) as the LC 630 (primarily to the education market)
and the Performa 630 (primarily to the home market). Models
included (under each of Quadra, LC, and Performa names) 630, 630CD,
631 CD, 635CD, 636, 637CD, 638 CD, and 640CD (whew!), which
Mactracker notes were differentiated, along with different software
bundles by different accessories, monitors, and hard drives. (As
well, some home-oriented Performa models used the less-expensive
68LC040 CPU). The whole collection was discontinued about a year
later in July/August 1995.
You're allowed to be confused.
In 1996, Apple bought Steve Jobs' NeXT, and the following year,
following a boardroom coup, he was named interim CEO. One of his
early acts was to clean up the messy product line.
At the 1998 Macworld keynote where he introduced the iMac, a slide illustrated a vastly
simplified field of Macs: there was going to be a
professional-level desktop, the Power Mac, and a pro-level
notebook, the PowerBook. The just-released iMac would fill a niche
for consumer desktop. And there was a hole in the space for
consumer notebook, which would soon be filled with the iBook.
By 1999, it looked brilliant. Four product niches, four models.
Simple and elegant, yet meeting everybody's needs.
Of course, reality is more complicated, even then. Each model
came in several configurations with different speed CPUs, different
hard drives, and/or different optical drives. In the bad old days,
each of these configurations would have received its own model
number, but now it was just an iMac or iBook.
In fact, if we look more closely, there are about as many models
today - and with about as short a life-span as a decade ago.
The More Things Change
As an
example, let's look at the iMac G5,
released in August 2004 and aimed at about the same midlevel
consumer market as summer 1994's Quadra/Performa/LC 630 series.
When initially released, there were models with 17" and 20" LCD
screens, and 1.6 and 1.8 GHz CPUs, and over the product's short
life-span, options for 40, 80, 160, and 250 GB hard drives.
In May 2005, these original G5 iMacs were replaced with what
Mactracker refers to as the iMac G5
ALS (also available in a variety of models), which had somewhat
upgraded graphics and processors. In October 2005, these were
replaced with the iMac G5-iSight
models; a sleeker case than the ALS models with an iSight camera
built into the top.
And these were discontinued in January 2006, replaced with 17"
and 20" Intel-powered models in identical cases.
You're allowed to be confused. Over a total life span of about a
year and a half, the G5 iMacs had three major model releases in
each of two sizes (17" and 20") with versions with and without
DVD-burning SuperDrives, different CPU speeds, and hard drive
sizes.
A decade previous, each different configuration of each
different model (and each different screen size) would have sported
a slightly different model number. Now they're simply marketed as
G5 iMac 17" or G5 iMac 20", giving the appearance of a simple
product line.
Change Is Good
I'm not complaining about the pace of change. It would make
little sense for Apple to hold off on upgrading its products while
CPU speeds and hard drive capacities improve. And consumers are
equally well served by being able to choose between differently
priced configurations of basic models.
And Apple's relatively small number of choices for each model is
much more straightforward than the ever-changing configurations
offered by, say, Dell. (I've counted as many as three different
Dell ads in a single newspaper issue, each offering slightly
different configurations of the same base-model laptop at different
"sale" prices).
But (as we saw) the G5 iMac had multiple configurations of two
different models and three upgrades all within an 18-month time
span - all with a single product name. I've got a 17" G5 iMac;
maybe you have a 17" G5 iMac purchased at about the same time, but
they're different.
Confusion Is Bad
I'm not convinced that consumers are better served by hiding the
differences than a decade ago when each of these slightly different
configurations sported its own slightly different model number.
A decade later, Apple is still selling a multiplicity of models,
each of which has a short shelf life. It's just hiding the reality
by giving them all the same product name. Of course, Apple has
often been noted for hiding complexity behind what appears to be
elegant simplicity.
