Need a New Ultrabook

I am a student looking for a portable machine. I will mostly be using Office, Chrome, and Visual Studio. I also don't want a laptop under 1080p. My current options are:

Acer Aspire S7 (2013)

Asus Zenbook Infinity

Sony Vaio Pro 13? (Heard about the Wi-Fi issue)

Lenovo Yoga Pro 2

Any suggestions?
