I highly doubt it these days, the whole macs have more power for graphic design bla bla is a load of crap. To get the true benefits of mac you need the whole iWank ecosystem, phone, laptop, network gear the whole lot.
Macs are great for non tehcnical people, much like my phag friends who don't drive manual because it requires too much effort.
And on topic, I actually use both. PC and Lappy for home and a mac air when I need a keyboard and not at home. Both have their benefits and draw backs.
Also mac air > iPad. 13" book is the same size but has a keyboard, more power, storage and external ports
