I see, it wasn't a comment per se as much as it was one of those tricky 'sponsor' inserts that we all have come to love here at the MacRumor forums.

The discussion about focal length leaves out one important variable -- sensor size. Not the number of pixels, but the physical size of the sensor. Without knowing that, it isn't possible to say whether the "shorter focal length" will mean a wider angle of view. If they stayed with the same sensor size, it will. If they changed the sensor size, it might or it might not.
The parameter that can be hard to find is "field of view" measured in degrees. Maybe it's buried somewhere. That's a useful parameter because it's an absolute -- not dependent on focal length or sensor size. If you know that, then you know how wide you can go, regardless of anything else. I've never understood why manufacturers don't say something like: "field of view is X degrees to Y degrees."

More ram, please. I don't know why they don't go higher especially with these faster chips and apps like the new GB that are supposed to do 32 tracks. Heck, it would get used even for keeping more safari tabs open without having to reload. Additional cost would be barely anything, I just don't get it.
Moreover, since new iPad (and iPhone) switched to 64-bit architecture this means that apps will now use more memory. And this means that new devices actually have less memory for storing actual data than the previous one. Switch to 64-bit architecture without increasing RAM size can be only explained by greed.
No hard feelings, just my opinion
I guess spec don't matter if all the developers are making apps and games suited to your hardware...Similar to xbox and ps. you don't ask how much ram does your PS has, its all same and developers will make games for your hardware...( unlike in PC or Android cos' there are so many variants that one has to worry about spec )
Battery is big news
The most important tidbit here is the battery. At about 25% less capacity but same rated run-time, the screen must've gotten substantially more efficient. I wonder if this means the IGZO display after all? I would imagine the screen is the biggest power draw, but I suppose they could get power efficiencies from other areas of the circuitry. Or is this just iOS7 being more power-efficient than OS6. Lower capacity battery I would think would charge more quickly as well.
With an original iPad, two iPad 2's, and an iPad 3 in the house, you'd think I wouldn't be tempted by this. But, strangely I think Daddy now needs his own iPad.

DaveI know it's old now but my iPad 2 is only marginally thicker than an iPad Air. I've put them next to each other and the Air is literally a couple of mm thinner.
I do appreciate that the screen is hugely different and it's speedy as hell, but it just annoys me that they're preaching about the thinness even though they've already been there before.
Meh. I'm not wowed by it, I really want a mini with Touch ID. *waits*

Went with the air today. Think the mini will be too close to my larger iPhone 6!
I like where your head's at... you meant the 5.7" iPhone 6 of course
You're not wowed by the thinner bezels and the 25% reduction in weight to go along with that retina screen and faster speed?
Repairability score a 2?!!! If I can't fix it or upgrade it myself than no sale!
Replaceability score of 10/10 if you have AppleCare

Eventually these things are going to be paper thin, weigh a half an ounce and someone's still going to complain that it's got a repairability of score of zero.

Even if you're dumb enough to pry apart a perfectly good iPad...
No.
A shorter focal length = wider angle of view = Neither good nor bad.
Bigger F stop number = greater depth of field = Neither good nor bad.
But with these small sensors even F2 will have infinite depth of field
and an even bigger number of F5,6 will only degrade image quality.
That's why small sensor compacts usually have fixed aperture and
simulate smaller apertures with a neutral density filter.
That's because iPads 3 and 4 are thicker than 2.
- iPad 2: 8.8 mm
- iPad 4: 9.4 mm
- iPad Air: 7.5 mm
Anyway, any 0.1 mm less is enough to feature an Apple ad.

No even Apple doesn't repair them. They just give you a refurbished one.
False. I got mine replaced twice and I asked them both times and they said lit was brand new. That's a common misconception though. You can buy a refurbished one for a cheaper price, but if you're under warranty, they replace a defected product with a new one.
But in the end, there's litterally no difference between a new and refurbished iPad and how they look and operate. Refurbished ones are like brand new, because they replace whatever isn't working with new parts and they do dozens of tests.
