iPad mini Review
by Anand Lal Shimpi & Vivek Gowri on November 20, 2012 6:10 PM ESTCamera
The iPad mini features a 1.2MP front facing FaceTime HD camera and a 5MP rear facing iSight camera. The rear camera shoots photos at 2592 x 1936, the same resolution as the 4th generation iPad. Both of the new iPads have the same f/2.4 lens, however the mini features a wider field of view thanks to its shorter 3.3mm focal length.
| Camera Comparison | |||||||
| Sensor | Resolution | Compressed JPEG Size | Aperture | Focal Length | |||
| Apple iPad 4 | 5MP | 2592 x 1936 | 3.4MB | f/2.4 | 4.3mm | ||
| Apple iPad 2,4 | 0.7MP | 960 x 720 | 344KB | f/2.4 | 2.0mm | ||
| Apple iPad mini | 5MP | 2592 x 1936 | 3.1MB | f/2.4 | 3.3mm | ||
| Apple iPhone 5 | 8MP | 3264 x 2448 | 3.1MB | f/2.4 | 4.1mm | ||
| Apple iPod Touch 5 | 5MP | 2592 x 1936 | 3.1MB | f/2.4 | 3.3mm | ||
Still performance of the rear facing camera is very similar to the 5th generation iPod Touch, and not as good as the 4th generation iPad.
The front facing camera is also similar to what you find in the iPhone 5 and 5th generation iPod Touch:
| Camera Comparison | |||||||
| Sensor | Resolution | Compressed JPEG Size | Aperture | Focal Length | |||
| Apple iPad 4 | 1.2MP | 1280 x 960 | 426KB | f/2.4 | 2.2mm | ||
| Apple iPad 2,4 | 0.3MP | 640 x 480 | 105KB | f/2.4 | 1.8mm | ||
| Apple iPad mini | 1.2MP | 1280 x 960 | 372KB | f/2.4 | 2.2mm | ||
| Apple iPhone 5 | 1.2MP | 1280 x 960 | 400KB | f/2.4 | 2.2mm | ||
| Apple iPod Touch 5 | 1.2MP | 1280 x 960 | 406KB | f/2.4 | 2.2mm | ||
Performance of the front facing camera is decent, and a significant improvement compared to the iPad 2 (you can see comparison shots in the gallery above):
Although I'm continually impressed by folks using tablets as their primary cameras at trade shows and press events, I don't believe the same standards apply to tablets as they do to smartphone camera systems. That being said, it's good to see continued improvements here.
Video
The iPad mini shoots 1080p video from its rear camera and 720p on the front. It looks like Apple is borrowing from the iPhone 5's encoder improvements here as video shot with the rear camera is encoded using High Profile H.264 (L4.1) at 17.1Mbps. The improvement in encode quality is possibly unlocked through software/firmware rather than an actual hardware change since this is still running on A5r2 silicon. In our iPhone 5 review, Brian pointed out that the A6 uses the same encode/decode hardware as the A5 but its full capabilities weren't unlocked until the A6. Given that encode quality has also improved on the A5r2 based iPad mini, it would seem that Apple limited earlier designs either due to a lack of time or to stagger its improvements across generations.
The front facing camera shoots baseline video at roughly 10.6Mbps, a huge improvement over the iPad 2 and iPad 3:
Video quality is definitely good enough for web use:

^+1I bought the original iPad and as many was amazed by the build-quality (stupid sharp edges excluded) and how fluid surfing the web felt considering the hardware. But I also within 15 minutes realised that it was badly memory-starved. Apple is an amazing company taking great pride in the user-experience of its products, but back then they goofed up badly.
I feel the same about the Mini. The CPU may be old but it's still fairly competent, the GPU still among the best, and the screen size may be close to perfect. But only 512 MB of RAM just ain't sufficient for today, even less for tomorrow.

Being slow to increase RAM and VRAM is consistently an issue with Apple. That's the case with Macs as well.For the iPad 1, it wasn't just that 256MB of RAM was small. Rapid drop-off in app support for the iPad 1, especially in games, is due to the resolution being so high in comparison to the RAM. The GPU was also underpowered compared to the resolution. 3rd gen devices have 480x320 screens and 256MB of RAM while the iPad 1 has 5.1x the pixels with the same 256MB of RAM. The 4th gen iPod Touch is affected by this too having a 960x640 screen with 256MB, but the iPad 1 is even worse with 1.3x the pixels of the 4th gen Touch. Support for the 4th gen iPod Touch in games isn't perfect, but is better than the iPad 1, which indicates that 256MB in itself isn't the limitation, but the drop in support for the iPad 1 is a combination of 256MB RAM with the higher 1024x768 resolution and the iPad 1 no longer being sold after 2011. The iPad 1 received 2 major OS updates (iOS 4.x and 5.x) post launch like other iOS devices so its OS support wasn't prematurely terminated.
I think the situation will be different for the iPad Mini 1. The iPad 2/Mini doubles the RAM to 512MB while keeping the resolution the same, which alleviates the poor resolution-RAM ratio of the iPad 1. 512MB of RAM represents the majority of iOS devices including the iPhone 4, iPhone 4S, iPad 2, iPad Mini 1, and 5th gen iPod Touch, of which given historical patterns, the iPhone 4S and 5th gen iPod Touch and perhaps even the iPad Mini 1 itself will sell into 2014. Given historical patterns, OS support for the iPhone 4S, 5th gen iPod Touch, and iPad Mini 1 should continue into 2015. Seeing it's only in 2012 that developers are really beginning to require 512MB of RAM, I don't see them already upping the minimum requirement to 1GB in 2013. Especially not when that eliminates the majority of their potential customer base, when those devices are still being actively sold into 2014, and receiving OS support into 2015. I think 2014 is a more realistic date for when apps will begin to stop supporting 512MB devices.
Personally, seeing the CPU was unchanged and the GPU is only 2x faster despite the 4x increase in resolution making it slower at native resolution than the iPad Mini 1 and iPad 2, I wouldn't be surprised if the iPad 3 loses app support before the iPad Mini and iPad 2.
Of course, just because apps continue to support 512MB devices doesn't mean the usage experience won't be degraded or sub-par. I can see that becoming an issue faster than app support.

I guess you reviews the Wifi-only version, but I'd like to see some analysis of the cellular connectivity options, especially what LTE bands are supported in the available SKUs.HighTech4US - Wednesday, November 21, 2012 - link
The mini lacks a GPS on the base model making it useless for using any map software with turn-by-turn prompts.The Nexus 7 has a built in GPS chip (and a very effective one and way better pin pointing location than a TomTom) and Google Maps works great on the Nexus 7 (you can download maps for offline use).
The lack of GPS on any tablet is a deal breaker for me.
Adding in the omission GPS with the other short comings along with its sky high price makes the mini just an overpriced iToy. The Nexus 7 is a much much better deal.

I think we have all forgot what gave us forgot what gave us 7" tablets. A "tablet" - i.e a tablet PC running Windows was normally in the 12-14" range. The JooJoo was a 12" tablet as well. Apple brought it down to 10" and sold a ton of those.At the same time a large number of more or less obscure manufacturers brought out 7" tablets *not* because 7" was considered the best compromise but because those panels could be bought dirt-cheap. But this also gave us this idea that a small tablet was supposed to be 7" while a large tablet was to be 10". I would say this is an anomaly, tablets have for the last ten years been larger than 10".
Maybe the "correct" size for a small tablet is in the 8-8.5" range? I was playing with my friends Motorola Xoom 2 (8.2", 1280x800) and while a bit heavier than my 7" tablet it seemed to hit the perfect size. Not so big or heavy as to be cumbersome, while still packing almost 40" more screen area.
Too much focus is being put on the device being pocket-able, how many really bring a tablet in their coat or pants? Just the idea of asking for a device to be pocket-able while still lacking a 3G/4G connection is just plain silly. Instead focus should be put on how it feels in hand but also how much space it occupies on a table. The 10" iPad was always too big to fit comfortable on my table while still having space for a cup of tea, a notebook, a plain book or the remotes for the TV and receiver.

"but in terms of repsonsiveness" In the conclusion.BSMonitor - Wednesday, November 21, 2012 - link
Incredibly too much... By the 4th generation of these, 32GB should be standard and 64GB a $100 upgrade...The BOM on 32GB NAND in this fashion is what? $15? Even if it's $20($10 x 2 16GB), they are getting a 1000% profit margin on that upgrade from 16 to 32 GB??
But they know we all have huge iTunes libraries we'd want on it...
Unfortunately there will never be a do-it-yourself tablet similar to the PC market. I stopped paying Dell and Gateway and HP a LONG time ago for their ridiculous profit methods.

Not sure if this has already been rehashed, but the pixel size is what kills the ipad mini for me. I have a Samsung Galaxy Tab 7.0 Plus, and I can SEE the pixels and it drives me nuts. The ipad mini has an even bigger screen with about the same number of pixels... Also, samsung fits in pocket, mini doesn't. I like the ipad mini's form factor, but again if it won't fit in my pocket it'll probably never leave the house...Rising - Wednesday, November 21, 2012 - link
I bought Nexus 7 when it was released. This is what i can tell you after few months of usage.."Its a good hardware in a crappy software". Iwould say the higher price premium on ipad mini is justified for software.
Most of the apps are zoomed over apps for Nexus 7. I hate that part of it. For example i use this app called apex launcher in my samsung s 3 and when i try using it on Nexus 7 all the icons are so small that they are hardly recognizable.
I donot understand why Google cannot optimize the apps to their own Nexus tablets.
Anand do you know whats stopping them from doing this?
