Since getting an Ipad I rarely use my PC however the PC is getting old now and is approaching retirement age. If I didn't need to manipulate and store photographic images I wouldn't bother to replace it however the Ipad is obviously unsuitable for this so a replacement must be found. The alternatives are a new PC and monitor or a 27" Mac. I'm currently leaning towards the Mac as I've been happy with the OS of the Ipad but I thought I'd best test the water before pulling the trigger. So the question is which system and software would you recommend?
