It says "(802.11a/b/g/n)"; the "a" should have told you.

No that wouldn't because I didn't know that "a" is a 5 GHz only spec. 
(Indeed I'd assume "a" is so old and decrepit with the low letter that 
it uses smoke signals or tom-toms or maybe something more advanced like 
a string between two cans).

What they should tell me is if it's 2.4 or 5 GHz or both.

So on the "Specification" page
http://support.apple.com/kb/sp580 they don't bother,

but on the "compare" page that nospam posted:
https://www.apple.com/ipad/compare/

They do.  So why bother on a mere "compare page" but omit it on a page 
with specifictations.  And don't pull out the "you should know or find 
out that "a" is in the 5 GHz band since the rest of their specification
http://support.apple.com/kb/sp580 goes into all sorts of particulars and 
details.  If that were so, then they shouldn't bother with it on the 
compare page https://www.apple.com/ipad/compare/ .

Your lack of knowledge is now Apple's fault?

They did tell you, you just didn't understand it.

They obfuscated it.  Out of courtesy to their customers they should make 
it clear on the spec page (as they do on the comparison page.  I'm 
chalking it up to an honest omission, as that is all is - of course you 
have to colour in language like "fault".

No they didn't.

I'm sure the vast, vast majority of the people looking at the spec page
know what 802.11a is.

> (as they do on the comparison page.)

Where the information is far more likely to be stumble upon by someone
who wouldn't know about 802.11a. Also, there's the fact that for the
vast majority of users 5Ghz and 2.4Ghz are meaningless.

the vast majority never heard of 802.11a since it hasn't been used in
about a decade, when 802.11g pretty much obsoleted it (and even before
that it wasn't that common).

But it's made a comeback.  The latest and previous versions of Apple's
AirPort routers and Time Machine have it as do every current Macintosh,
iPad, iPhone (except the 4s), iPod Touch, and Apple TV.

802.11a support is there only because the chipsets support it so it
costs nothing to include it. 

it definitely has not made a comeback and it wasn't all that popular a
decade ago either.

And earlier models of all those products that supported 802.11n used
chipsets that did not have support for 802.11a?  I wonder why later
chipsets support it and earlier ones don't.

they did. 

802.11a first appeared with intel macs, with 802.11n support coming
later when the airport base station with 802.11n came out which
included 802.11a and shows up as '802.11n (802.11a compatible)'.

In general (outside the world of Apple), 802.11n can operate on 2.4GHz
or 5GHz. A 2.4GHz-only implementation will often support b/g/n only, but
once you add the physical antenna and radio to support 5GHz, you get a
for free, so you may as well support a/b/g/n2.4/n5.

While 802.11a was rarely used, you'll still run into it on pre-802.11n
gear where 2.4GHz is extremely congested, so it's a "nice to have" even
though most people will never see it.

Also, inside the world of Apple; why do you believe that it's only
outside the world of Apple?

Pure ignorance, no doubt.

Because I wanted to make it clear that I'm talking about the protocols
in general, and not get bogged down in "Yeah but Apple never released a
'x'" discussion.

I was connecting specifically on why Apple added an older, lesser used
standard (802.11a) on newer devices, but you snipped enough context to
make it appear I was bashing Apple when I was not.

Good job.

802.11a is not a subset of 802.11n - so it's not making a comeback.

802.11a is in the 5 GHz band, but only provides 20 MHz channels.

802.11n is in the 2.4 and 5 GHz bands.  Not only can it set up a 40 MHz 
wide channel (in either band) but also has multiple antennas to increase 
the bit rate to upwards of 600 Mb/s.

By definition, leaving out pertinent information is obfuscation.

"The majority of the people looking at" it probably understand less than 
20% of the items on that page.

So down at this end of the discussion it's meaningless, but up a few 
lines ago everyone's supposed to understand the implicit meaning of 11a?

You're a very strange fellow Lewis - just as much for the nonsense you 
spewed here as for snipping out the rest of what I said.

They didn't leave it out, you just didn't understand it. That is not the
same thing.

The sorts of people who would be looking at the specs are going to be
people who understand the specs. Other people will be looking at a nice
chart comparing the models.

You're talking about two entirely different documents for two entirely
different audiences.

As I said in an earlier post it's more likely just a simple omission by 
Apple.  But that nice, plausible explanation induced you to snip it out.
