Heres my experience and my 2 or 3 cents

- Sorry in advance if its long
Im a Full time Teacher and Motion Graphics Designer.
Been a Windows user all my life and i like Win 8
So heres my dilemma at this moment:
- Need a machine with more powerfull GPU
- Having all peripherals triple monitor setup and a lot of peripherals logic would be nMP. Well to expensive and way overkill ATM for what i do.
- So im thinking seriously to replace completely my PC with iMac 27 Full Spec
Now, would i like to be able yo exchange parts as i do in my PC? Yes
Is it possible? No

Do i really need OSX? Oh Yes
So in a few months ill trigger the "Buy Button" and get my self a Imac (still waiting to see what comes out on the Mini side)
Heres a reason that 1 person needs a Imac instead of a Win 8 PC
OSX gives me the freedom to run any software that i need, even if only available for Win ill just install my Win 8 Licence on the Mac and there i Go.
Please dont suggest Hackintosh to me. Ive tried it and didnt liked it. Very insecure. I work with the machine, i cannot afford 1 day to troubleshoot why its not booting or why is freezing

(im not against it but its not for me)
Another though:
Last month i offered my Wife a Imac 21.5 I5 2.7Ghz 8GB Ram 1TB HDD - 1350€ with 20% cashback that i used to buy her a iPad mini Retina for 100€

I also got extended warranty of 3yrs for 80€ so a total of 5 years warranty on this machine.
She has besides OSX
- iPhoto (Our favorite app ever to organize photos)
- iWork (Docs, spread sheets, keynote)
- iLife (iMovie, Garageband) - This she doesnt use it
But the point is. Its not only hardware that we have to count for when getting a Mac system its a lot about software and if you are going to be using it than you will see that the prices are not that far away when purchasing similar software for the Win machine.
Wow what a big post
By the way both sides have pros and cons as everything in life.
Design wise there's nothing comparable, its just beautiful.
