Most so called comparisons are by people who are able to build their own PC from scratch & can achieve a significant saving this way.
Naturally these people ignore the fact that the average person cannot/has no wish to go this route & also refuse to recognise the quality of Apples design and casing materials.
They also ignore the fact that those home grown PCs use sub-standard parts from fly-by-night outfits who don't need to practice quality control because it's not like they're going to be responsible when the thing stops working in 6-10 months. And when something does stop working the "build it yourselfers" just upgrade to a new, cheap, part.
Those of us who use our machines professionally demand they keep working for years, not months.
At a user-facing UI level, it makes no sense to merge OS X and iOS. However, it would be great if the APIs shared a lot more commonality. Do we really need both NSColor and UIColor? NSFont and UIFont? If Apple dedicated some time to merge the foundations of OS X and iOS, there's no reason why porting apps from iOS to OS X shouldn't be trivial. Imagine the Mac App Store being as vibrant as the iOS App Store. Worth Apple's investment in my opinion.
Well, iOS and OS X are based on the same operating system. iOS was split from OS X so I think it's kinda funny for people to talk about "merging" them, they're already merged. The differences are primarily ones of UI where iOS needs to work with a touch UI while OS X works with a mouse driven UI.
But, inevitably, some things get more work on one platform than the other. And thus you might have UIWhatever that is more advanced than the NSWhatever it was based on in the past.
I don't think porting will ever be trivial or that it should be, but I think this is the right approach-- things are fundamentally the same so that making Mac and iOS versions is not too much work, without going down the path of compromise that is "write once run on both platforms"-- something that would result in lower quality for both platforms.
I think the new Mac Pro will come in a "mini" flavor. That is to say, I think it's a reasonably economical platform. So they can make the high end that they showed off, but by simply replacing the GPUs & CPU, they can make a cheaper version. I wouldn't be surprised to see models as cheap as $1,299 (with more pedestrian CPUs and maybe a single GPU)
I think it's hilarious when people accuse writers of being "biased". Obviously, anything that agrees with your ideology is "objective' and anything that doesn't is "biased" so you can just reject it out of hand.
Accusation of "bias" is like saying "I reject all of reality that disagrees with me!"
Frankly, the people who pretend to be "unbiased" are usually making worse arguments than those who aren't hiding behind faux objectivity.
