Well since it's mentioned now, I'm gonna join in too. 😀
It's got nothing to do with Windows, it's more to do with the direction Apple is heading. What's the bonus of sticking with Apple?
As a long time Mac user (20+ years) and one that came from their then core market (creative professionals) I really see no benefit to me in being an Apple customer these days.
I still run Mountain Lion on my photo editing machine (because it's about as rock solid as anything since Snow Leopard and I want my computers power to go to the editing software I use, not just running the OS), a machine I was able to upgrade aftermarket, but in my day job (ironically, selling and fixing Apple products) I have to use their latest stuff, sell closed down (waaaay over priced in my country) systems and witness first hand on a daily basis their slipping quality and appalling performance of their computers. Add to that I have to deal with Apple directly and know full well that the computer department is just an inconvenience to them. They just want to sell more phones and tablets.
I remember when Aperture first came out. Wow! I was amazed. I did all the fancy Apple training on it. I used it. I endorsed it.
Gone.
Buy an iPhone. Wear the watch. Rent movies on an iPad.
I don't necessarily want to move to Windows, but all I do is edit photos (Lightroom & Photoshop) and browse the web (Google Chrome now that Safari is ****), why spend more than I should to stick with Apple?
