I was a sworn PC guy for YEARS, Dell, Gateway, Compaq, EMachines, you name it, I had it all. Ran Linux Ubuntu on them also. Bought a Mac Mini a few years back at the same time I bought my iPhone. Will never go back to PC. The Mini is awesome for what I use it for, but a bit slow when I process HD video (GoPro footage) and slow when I work with RAW photo files. For this reason, I am looking at the iMac. The one I want can be had for $1500, and that comes with the 1TB drive and the i7 processor. Go to the Apple site and even check out the refurbs- they are just like buying new, and the price can vary by a couple hundred dollars.
As for Mac's syncing with iPhones, you have to use iPhoto and the Photostream. People looking to drag photos over are still living in the "olden days" of PC mentality, if you ask me. I can get my photos without having to connect with a USB cable, wirelessly, and the photos open right up in the application I use for basic editing. How easy is that? The days of connecting cables and hunting for the DCIM folder/camera/photos/view-thumbnail is over! Embrace the new technology. I also have jailbroken my iPhone, so I can use Cyberduck to transfer them by the "antiquated" method if I choose to do so.
Mac's do function differently from PC's, and that's where the learning curve takes over. I equate it to the difference between having an Android vs iOS. I can put whatever I want on my PC from whatever source, but I have to search a lot harder and pay for the stuff I want on m Mac. But, the positive side to this is the programs are a lot more controlled, and the chances of getting a virus from some shoddy EXE file are nil with the Macs. I haven't had a virus in 3 years, no noticeable slowdowns, no blue screens of death, no NOTHING that I experienced routinely with PC's. The only PC I own is a small netbook. It runs Win7, which is pretty decent. But it too has crashed and locked up- something I rarely encounter on my Mac.
As everyone who owns a Mac will tell you...it just plain WORKS. If you are like me, I run Apple TV, iPhone and the Mini. They all function seamlessly with each other, and work like brand new year after year. That's why you pay the bigger bucks- for excellent customer service with people who know what the hell they are doing, not outsourced third-world help. They provide contstant updates and keep the OS on the cutting edge, and upgrading and programs don't cost $400-$600 a pop like some PC software. I use Pixelmator and Gimp, both Photoshop like programs, and between the two they cost me $5. There's no contest.
I'd say if you are not sold on the iMac because of price, try the Mini first. You can get a well-equipped one used and spend around $500. Then just experience the functionality. If you're like me, you'll be sold and want the iMac. Or, you might hate it and go back to PC. But you definitely won't have any problems selling it if you do! I sold my old Mac Mini for $390...and I bought it on Ebay for $350...lol.
