Battery life is approximately halved if you use Bootcamp. Apple hardware is highly optimized for Apple software, and Apple software effectively utilizes Apple hardware.
Again, it's one size fits all. Apple is like that one car that can get you across the country on one tank without having to deal with loud ambient engine noises or a hazard light that just randomly lights up. Android would be those cars that can either scale a 60 degree incline, carry 3 tonnes of cargo or get you across the country in a third of the time. All of which will not perform with the efficiency or ease that the Apple provides.
Yeah. I know we should keep it on-topic here, but I would just like to take the opportunity to add a couple of points:
1) I think the car analogy is apt in one more way: Would you pick a car on the engine specs alone or would you pick it based on the whole picture? I mean, it's basically the same with computers. You have ergonomic/comfort such as keyboard and trackpad. You have visuals like the overall design and the screen you're looking at. You have sound quality, and so on and so forth, until you come to one of the must fundamental parts of all: the OS itself. If it suits you, then go with. If a BMW suits you better than a Nissan Micra from the early 90's, go with the BMW if you can afford it.
2) I see a lot that Apple stuff are overpriced. I disagree with it. If you look at the specs alone, then you are actually paying about the same kind of money as you would with a Dell or a HP Elitebook. The difference wouldn't be large at all, and factor in the support as well. Also, considering the design wizardry it took them to make their laptops so thin, quiet, good battery life and small weight along with their software team CREATING their own OS and a whole ecosystem around it - then they're not overpriced. You may very well be paying a lot of money here, but think, there were a lot of invested money (and I'm excluding marketing) going in to create those laptops (and phones/tablets, that use their own inhouse hardware design for SOC's or CPU's that are pretty damned impressive compared to their competition).
At the end of the day, the day that Dell, HP, or Microsoft delivers the same premium stuff that Apple does with their own superior ecosystem, that *will inevitably* be the day you will see premium prices on their products as well.
I know it's popular to crap on Apple and Beats around forums instead of trying to see a bigger picture going on, but let me just quote one of the most influential people on earth when it comes to computer science, both software and hardware wise, Linus Torvalds:
"I have to admit being a bit baffled by how nobody else seems to have
done what Apple did with the Macbook Air – even several years after
the first release, the other notebook vendors continue to push those
ugly and *clunky* things. Yes, there are vendors that have tried to
emulate it, but usually pretty badly. I don’t think I’m unusual in
preferring my laptop to be thin and light.
"...I think one of the things that made Apple able to do this was how
focused they’ve been able to stay. They really have rather few SKU’s
compared to most big computer manufacturers, and I think that is what
has allowed them to focus on those particular SKU’s and make them be
better than the average machine out there.
"So that kind of focus takes guts. I’m not an apple fan, because I
think they’ve done some really bad things too, but I have to give
them credit for not just having good designers, but the guts to go
with it. Jobs clearly had a lot to do with that."
In case no one knows who Linus is, he's the founder and creator of Linux.
Also, in case you think I'm an Apple fanboy, no I'm not. I still use Windows at work, I regularly set up both Windows and Linux servers at work, I use vSphere at work, I use Windows on my computers and laptops at home. The only Apple products I have are my iDevices.
