Looking for constructive advice re: Mac laptops

BF89905

Hello,
I'm looking go purchase a laptop in the near future. I was originally focusing on ultrabooks exclusively: Asus Zenbook 31A, Sony Vaio PRO 13, Samsung Series 7, and a Macbook Air.

I've used Windows at home for years and a combination of Windows and Mac OS's at work for the better part of the past decade.

This morning I discovered Apple has a refurbished section go their online store that has led me to narrow my options down to the Samsung Series 7 Ultrabook, and two refurbished Macs.

I would really appreciate the constructive opinions of others familiar with either of these laptops (or you're simply tech savy) before I make my decision to purchase. Please look over the following details and contribute your constructive feedback to this thread. Thank you very much for your time, efforts, opinions, and sharing your experiences.
