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?
