Agree to this.
We all know we can get better specs buying a Windows machine. You don't buy a Mac because of the hardware.
I have been using OSX since MS put Vista out (the last straw). However, I do run Win 7 in a virtual machine as it has a couple of applications I cannot get on the Mac side.
OSX isn't more optimized, but a simpler operating system that actually does far less than Windows 7 and 10. This can be a very good thing but also as stated it is "less than." I still remain an OSX fan but some of the thoughts in this thread make me scratch my head.
OSX office suite - completely lackluster. It is good if you don't really need a suite. If you do need one, chances are you'll find the MS counterpart Office to be vastly superior. I happen to like OSX suite for unimportant things or personal things. When I do writing that goes to clients and businesses you can be sure it is done with MS Word and spreadsheets done with Excel etc.
Outlook vs OSX mail - I use OSX mail and find it quite usable and friendly sans the things I miss from Outlook. I consider the latter a more featured mail program.
As for hardware, Apple has proven it can be quite successful with form over function. Apple might adopt a new communication feature (Thunderbolt) but it remains tepid when it comes to CPU and GPU and often 1-2 generation behind on some models. Can they be replaced? In general - NO. Many many PCs you can dive in and replace vital parts or add to them internally. We all know Apple, remains elegant at the expense of this option in general. However, you can certainly make a jungle of cords and cables on your desk if you want to add externally.
So am I bashing Apple? Well...not really, what it does it does well enough. Do I prefer the OS? Absolutely. What the PC has is the ability to far more (specs) for the price in general, more accessible for upgrades and replacements and a far larger set of applications are written for Windows than there are for Mac. Even software written for both often seem "less than" on the Mac (Quicken comes to mind) and so forth.
I'll remain with my Minis (older models as the new ones are anemic) and my rMBP and exactly the applications that I need (including virtual Win 7 to run the missing apps on the OSX side). Now that the Mac Mini Pro or Mac Pro is out of most people's reach costwise, I'll just hold out until the day I end up building another PC and groan as I use Windows.
