Every platform has its strength and weaknesses, and the Mac is no exception. PCs are built for gaming since all games are developed for that, while Macs are built for work like web designing, HTML5 development, photo editing, music recording, iWork, and other creative, professional and office stuff.
Yes, Macs have limitations in gaming, but that’s what iPads are for. You create games for iPads using a Mac, and that is what is intended. You cannot create iPad, iPhone apps using a PC and that is its weakness.
