I have the same question - are there enough benefits to justify switching to Mac? I've read a lot of forums about OS X vs Windows and the hardware they run on. This is my current opinion, with no offense intended to any of my brothers or sisters on this forum.
Dr. J. is correct that "Mac hardware is simply superior to most of what is out there." It is correct because most PC hardware is low end. But if you compare the same or similar Intel chip, RAM, ssd, etc., they are in fact the same or similar. I got my MacBook from my daughter. She bought it in 2007, the same year I bought a Dell Vostro 200 desktop. As Rick pointed out, that model MacBook had problems, and we replaced the hard drive a week after the warranty expired, and later the battery. I never had a problem with my Vostro or its Windows Vista Business Edition, and everything is still original (granted, it is a desktop). But I also read that the subsequent MacBooks were excellent. But not, in my opinion, better than my Toshiba Satellite Laptop, which lasted 10 years until the fan died. It was also all original (granted, I had XP Pro - Windows Pro editions were much better than Home ones).
I also agree with Dr. J. that Apple software is excellent, at least what I've used in the iPad and what I've read about, except MS Word for Mac that had problems with Hebrew. MS Office 2007, which I've owned and used since 2007, is excellent, and has no problems with Hebrew (I did the camera ready copy for my book with it, with lots of Hebrew). I also agree with Dr. J.'s comments about IE - that's why no one uses it! The vast majority of Windows users use Chrome or Firefox. Regarding viruses, etc., we all buy antivirus programs. I've never had a virus do damage that I know of - those programs did their job. If you're not a student or staff member somewhere, you pay about $29/year for it.
From what I've gathered, and what I hope to discover in my adventure is that the overall OS X experience outweighs the Windows one. I'm especially tired of the constant updates and the time they take. And, in my case it comes down to software - Scrivener still has more features in OS X than Windows, and I want to use Sente 6 with it, which is only available in OS X. I also want to experience the Mac version of Accordance and see how it integrates with the iPad.
I hope to comment on the overall OS X experience in the coming months, almost exclusively in relation to Accordance and productivity (Scrivener, Sente 6, and whatever else I find).
