I have had PCs for all my life until I purchased an iMac24 this past spring. I had visited with my brother in OKC in February & used his & in his computer cove he has the mac & several PCs set up. I really liked what I saw. As his career is IT and he does heavy graphic/videos, his recommendations fly high with me.
My uses are the same as your sushiman. I dont game & do a lot of you tube, some music, many forums, but MOSTLY graphics..
In my estimation there is no comparison to the quality of pix. I had top flight flat HD screens with my PC & If I have the computers next to each other with same pix on, well it is very evident.
Now the men & women here are much more knowledgeable about the nuts and bolts (as my brother is). The understand performance, components etc. I am an end user & one of those people who just wants to know what to hit to do what. I just know I want less hassle. I too hated the slowness of the PC with all the security programs.
I also know that eventually Macs will probably be victims of new virus developed JUST FOR THEM.. for now safe.
There is a learning curve. My brother told me it is intuitive.. well, to a point. Much of the operation is different & as it has Safari (I had been using Firefox) there were two things to learn. 4 G RAM & 1 terabyte HD .. so it is pretty fast.
If you have convenience & time luxury, go to an apple store & use one of the machines.. they don’t mind if you come & do that often while you are deciding. Also these stores are quite different than PC places.. Approach, methods etc. LOW key, not any pressure..
I know the new PCs OS seems promising but I truly dont know, just what I read from others..
Just sharing my experience & thoughts
Good luck.. there is nothing worse than having projects/deadlines & a computer that is either dead or very uncooperative!
