You need to spend more time with Nexus 10. Benchmarks of GPU of iPad 4 blows the Nexus 10 out of the water...by a huge margin! I can post raw data to prove my point if you want.
I'd agree the benchmarks blow the Nexus out of the water; however, whether or not this actually matters to the average consumer comes down, IMHO, to two things:
- what's most important to them ('experience'? Price? Specs? Etc.)
- what they actually use it for
(Disclaimer: I do IT work for the government, and have spent plenty of time with both, so I do have some experience with this subject.)
Sure the iPad 4 blows the Nexus 10 out of the water. Does that matter? Depends upon what the user wants. If they want a tablet that they will do much gaming on then absolutely it'll matter. If they want a more 'cohesive' experience I still lean towards the iPad. If they've 'bought into' the Apple ecosystem, then yes, they'll want the iPad.
However, while I agree that the Nexus 10 does get bogged down, I will also say that in my experience/testing, 99% of the time it slows down due to doing something graphics/processing intensive, such as playing a game, using any app that is both graphics and processing heavy, etc. Playing music, scrolling through, watching videos, etc. are all pretty much seamless.
So when advising people to purchase one or the other I will ask them to consider usage first. Once that's done, I'll ask them about the other factors - e.g., how 'bought in' they are to other ecosystems? Do they want it to 'just work' or do they want to hack the heck out of it? How much of the overall buying decision is weighted by price? If they DO want the speedier graphics and seamless experience, are they willing to pay extra for it? Essentially, I ask them to conduct a mini systems analysis.
Once that's done, *THEN* I tell them to go online to a reputable source of reviews that puts an eye towards both the geek AND the mainstream consumer. After all that's done, then they make a decision.
In my experience, if people want to hack the bejeezus out of it, use it as a glorified e-reader, for documents, own nothing else Apple, and/or price is a big factor, they usually end up with an Android device. If they want it to 'just work', if they want that seamless/cohesive experience, if they want to 'get as much out of it' as they can while still maintaining that seamless experience, if price is not a huge factor, or they own other Apple products, they usually end up with an Apple device. 100% of the time I've counseled people to buy one or the other using the above process, they've been happy, with ONE exception - and THAT was because the wife was buying one for her husband, and completely misunderstood HIS priorities in getting one. LOL
Don't get me wrong - I've always leaned towards, and still lean towards (somewhat), Apple products; I own 2 Mac Minis (one of them a quad-core server), an iPhone 5, an AppleTV and some other stuff.
BUT I tailor my usage to my needs, and most people will, I think. I bought an iPad 2 a year ago or so, and I ended up selling it because for what I use it for (reading, surfing, email, music, the OCCASIONAL game such as Angry Birds, occasional document editing, etc. - and that's it), using an iPad to is like spending $5000 to up-armor and lift your 4Runner so you can drive across the occasional gravel road.
That's my take, anyways. I will say that I agree with you overall - if I was going for a 'full size' tablet I'd go iPad 4; but for a 7" tablet, well, let's just say I've played with both the iPad Mini and the Nexus 7 and for the price there's no comparison.
