Overall, I find the quality to be top notch, and Windows 10 to be just as stable (if not more so) then OS X. , I prefer OS X for terminal work, Apple ecosystem, backing up to name a few
After a week of playing with the Surface book and re-acquainting myself with Windows, I have to agree that OS X has a polish and responsiveness that Windows only matches in its dreams.
However, OS X is not without it's annoyances - its just that we all learn to live with them. For perspective, I find that even using somebody else's
Mac can be frustrating if they haven't got things set up the way I'm used to (sorry, but how do people
live without "Applications" and "Terminal" in the dock, and default finder settings that are self-evidently
wrong ?)
Also, when trying out a new OS it is tempting to jump right in the deep end: I think the second thing I installed was the Windows Linux Subsystem (which says "Work In Progress" in large, friendly letters). Next, I plug my SB with the Windows equivalent of a retina display into
two nonretina monitors, set up a 3-display system...
then detach the tablet section. The results... lets say they could be more slick and seamless, with less need to go back and tinker displays preferences, but so far it hasn't crashed or become completely unusable without a reboot. More perspective: in my experience, Macs sometimes crash completely on connecting an external display (usually when I'm just about to give a presentation and have 3 powerpoints and a couple of demo websites all cued up).
The big stupid with Windows 10 is that it hasn't quite got rid of the Windows 8 debacle of "New" and "Old" applications: so there's the familiar "Control Panel"
and the new "Settings" app, each with a different but overlapping and interconnected series of options. (Pro tip: if you're new to Windows, use Settings, if you're a verteran use Control Panel).
I much prefer Windows on file/directory management.
I remember Finder being one of the stumbling blocks when I first switched from Windows to Mac. Unfortunately, Windows Explorer seems to have got the ribbon treatment.
On the other hand... Windows filenames, directory paths etc. are a pain. My biggest pain so far has been going through my work files and fixing weird characters in file names that OS X and Linux take in their stride but cause chaos in Windows when you come to copy files or back up. I don't create these (I'm pre-conditioned against putting slashes, quotes, angle brackets etc. in file names) but I do have to deal with other people's files.
Then, oh my god
drive letters - seriously, CP/M called from 1978 and wants its drive letters back. There's a right way to organise filesystems, and Unix is it.
I prefer OS X for terminal work,
Absolutely, although give it another year and the Windows Linux Subsystem might have that covered. In the mean time there's Cygwin and/or the "bash" shell and selection of unix utilities that comes with Git for Windows.
Apple ecosystem, backing up to name a few
The "new" Windows 10 "File History" backup facility seems to be their answer to Time Machine - although it has nothing like the gloss. Also, its just file versioning/backup so you really have to create a separate system disc image for disaster recovery. That said, treating file history and system disc imaging separately is probably the better strategy in the long term (although Time Machine is super convenient and friendly, the backups do grow like topsy...)
Overall - if you offered me a choice of OS X and Windows on the same hardware, I'd take OS X any day, but if Apple don't offer the hardware you want don't rule out Windows - just allow time to adapt.
I got the Surface for the moment because:
(a) I'm pretty sure that when/if the new Mac desktop lineup materialises, I'll have a hard decision on whether to choose that or build myself a PC Windows/Linux mini-tower. If what emerges is a dumbed-down, 10% thinner, non-upgradeable iMac with an inflated price point, and no "headless" options then I think the Mac will die as a serious computer platform (it may live on as the ultimate Facebook experience) So I want to re-acquaint myself with Windows and the SB is the flagship Windows implementation.
(b) I kinda have a professional interest in the tablet/stylus aspect of the SB so I can justify splurging some money. I think its a keeper as my main mobile "productivity" device. The main question mark is over my web development work (which is a real strong point for OS X) but there are good arguments for doing
that in a Linux VM.
TLDNR: I would never switch to Windows for the sake of Windows, but if Apple doesn't offer the hardware you want, its a very viable option.
