But come on guys, let's not turn this into another Mac vs PC debate, the OP asked a simple question. And anyway, does it really matter whether you have a Mac or PC, either or is not going to make you design any better, it's just down to personal preference. With my experience of both Mac and PC, if you can afford it, I would always recommend an iMac.
I certainly don't want it to descend into a Mac vs PC debate.
With the thoughts being
"Well Apple are better because well...it's Apple and they make superior things, and I don't know anything else except that Apple are the best and I worship everything they bring out and dismiss all other makers of devices!!!"
However, if the debate is sensible, Mac vs PC, specs vs cost etc. And nobody slurs anyone else in a post - then I'm good with a healthy debate on which is better in terms of spec/cost.
For what it's worth - I am getting a brand new Mac in a few weeks - it's costing €6.5k.
I spec'd the exact same PC setup - and it only costs €2.5k.
Why am I going Mac - reason is fonts fonts fonts. Unfortunately already in a Mac studio and everyone else has Mac fonts which don't work on a PC. However, PC fonts work on the Mac... or something like that. OTF has not taken over.
Another humdinger, I got technical specs from a printing company who only accepted PDFs created using a Mac, PC PDFs were not 'allowed'.
I was working on my PC and I made the PDF and I sent it and little did they know!
I'm from a generation where the Mac was the best piece of hardware for software back in the late 90's and early 00's. The PC was a humble Office computer, they weren't designed for anything other than a bit of Word processing.
But - the PC has taken hold within the market - at the end of the day it's the same intel processor in your Mac that's in my PC. It's the same Raedeon Graphics card, it's the same Corsair DDR3 RAM.
The only difference is the OS.
I've never really been a fan of the Mac OS UX. And Windows is pretty gnarly too.
But in my mind it's 6 of 1 and half a dozen of another when it comes to the comparisons.
========================================================
Anyway - what's the best Mac to get - whatever you can afford to get.
What's your budget?
