Mac or PC for programming and college?

Ahh the age old debate! Anyways, I'm going to school for computer science, but I want to mainly focus on creating mobile apps, but I'm sure that's not all I'll be doing in class. I want a laptop that has good specs (i5 or i7, 8gb of RAM, at least a 1080p screen, integrated graphics is fine), somewhat lightwight (no heavier than 4 lbs) and that is no larger than 13.5 inches. I would like to stay under $1300, but I can go up a couple hundred if I needed to. I am mainly going to be programming for android, but I would also like to dabble in iOS if I ended up getting a mac. So far my two favorite picks are the Lenovo Yoga 900 and the Macbook pro. However I'm torn, because I'll get better specs with the yoga for cheaper plus the touchscreen, but getting a macbook would allow me to use OSX and develop for iOS. I've never really owned a mac except like 10 years ago when I had a first generation iMac for like a month (it was a given to me by these people I babysat for but broke like a month later), but other than that I've always used windows. I have a really good desktop computer that I can use for intense things, but I need a good laptop that can last throughout the school day and is also comfortable to code on. So what you do guys think?
