I assume this discussion is already more about the transition from desktop to laptop, than about the PC to Mac etc. Have you looked at Windows on 27" Thunderbolt display? The first time I saw that display with Mac OS X rendering on it, I thought: "Wow, that looks awesome. The glare from the glass is bothering, so there's that, but placed right in the room, it's totally fine and well worth for that size and clarity.". Then I went to the specs and saw that the PPI of this monitor was exactly 6 points above my own (1920x1080, 21.5", 102 ppi vs. 108 ppi)? Is it possible 6 points to be such a differentiator? Of course, it turned out it wasn't - I immediately tried windows on the same Mac machine and there it was - everything looked almost as badly as on my own PC. So, I asked the guy that owns the machine (he is a graphic designer), why there is such a difference and he said: "Microsoft simply doesn't care enough about detail. Check the default icon sizes in the OS - OS X's icons on regular-density display (non-retina) are 4x bigger (512x512 vs. 256x256 on windows) and on retina this grows to 16x more pixels (1024x1024)." So factor #1, IMHO, is people ditch Desktop PCs because of Microsoft's lack of flexibility and innovation - they decided "If we have a monopoly over desktop computing, why should we care what our users say? They still buy 'it'.". Factor #2 - Microsoft still has the numbers!!! They have locked the enterprise tight, and still don't care about "personal" user experience. So we have this giant corporation that gets enough money and has no incentive to innovate and we hope it will bring us the great singularity of software and hardware we have all been waiting for... And the last factor I will point out is relevant mostly to developers - Mac hardware runs it all. Then having a Windows and a Mac machine, doesn't really make sense, both as expenses and simplicity of work. Apple made the, arguably, "evil-corporate" decision to be totally in control of the hardware running its OS. So you, developers, have the option to buy: - iMac, that sits tight on your desk + Macbook (probably Air) for your work on the go; - Mini + Thunderbolt + Macbook (probably Air); - Pro + Thunderbolt + Macbook (definitely Air after what you paid for the previous 2); - Macbook Pro. Well, as I see it, most developers are headed for the Macbook Pro with eventually adding a Thunderbolt. For developers in need to support the Mac ecosystem, this is not even #3 reason - it's #1. I had to make this transition and I am glad I did, because Mac OS X turned out to be no less then great, and although smaller in size, my 15.4" retina display got me into the 21st century. :)
