Can't convenience be benchmarked? Portability is convenience, and portability is weight. Weight can be measured. An iPhone is lighter than a Macbook.
You can't do "everything" on a desktop operating system. There are things you can do on the iPhone 6, for instance, record high res video with the camera, that you can't with the MacBook. There are apps that are exclusive to mobile.
Yep, Modern Combat 5 is amazing and one of my favourite mobile FPSses. I gave it as an example, because your own example of "Crossy Roads" was ridiculous as there are far more advanced games than that for the iPhone.
Dude... You CANNOT measure convenience. Convenience is subjective, not objective. You can't test convenience, and it is not universal for everyone. For instance, your "weight" is more convenient to you. However, a full desktop operating system is more "convenient" than weight to me.
Like I've said a million times, they are two completely different devices, there is NO reason to compare a laptop to a phone. No reason.
Enjoy your iPhone, as I am. Let people enjoy their MacBooks without belittling them.
I don't care what Modern Combat 5 is compared to Crossy Road, it's not comparable to any modern FPS on a desktop. Again, comparing a mobile game to a desktop game. No point.
Your MacBook is defective. My MacBook Pro 2008 Core2Duo with 2GB of RAM can scroll through PDFs without lag. I would go ahead and get Apple to replace your MacBook, unless you're trolling.The MacBook is underpowered when it comes to 3D gaming, compared with the iPhone.
It also seems to be underpowered for PDF documents, incredibly, it struggles with the most basic plain text documents! I've tried all sorts of PDF readers including QuickView and Skim, and my iPod Touch can scroll through PDFs smoother than my Macbook with any of them!
