I recently made the switch from Mac to PC at my office, as have a few others...
- As far as I have seen, there is no real difference in the Creative Cloud Software.
- I think it's personal preference which you go with. I like the Mac OS better, but I got a far superior PC for the price and can upgrade it as needed. Graphics cards are becoming increasingly important and a PC can give you more options.
- Yes, we have multiple editors passing off projects between Mac and PC with little issue, besides them occasionally seeing file paths differently. Then it's just a matter of reconnecting.
- I think it's worth it to go with what your comfortable with. I do worry that Apple isn't giving the professional users as much attention as they have previously and their hardware isn't as robust. With how quickly technology is changing and the inability to upgrade parts in a Mac, they may not have the lifespan it once did.
After doing a bit more research yesterday/today I'm leaning towards IOS. It seems like their are less gaps between PC & Mac now than there used to be but I just like the look and feel of Macs. Also my IT admin claims the specs are identical across my machine options (it's just whether its a Dell XPS, Lenovo ThinkPad, or MacBooks). I have no proof/research to back this up but I think I'll get more power from the same specs on the MacBook.
