Rainbow Six 1-3 and the first Ghost Recon were a huge reason that I fell in love with PC gaming. Those with Red Alert and Age of Empires. Awesome games.
I just got mine in yesterday. After some reworking of the colors and turning the brightness down, I'm really pleased with it. Blacks are much deeper than my cheap Asus IPS monitor it is replacing. Colors are on par. Gaming is awesome and immersive with the curve. I took a risk getting it...
I too was going to go with the mini, but Thursday night I found myself ordering an Air. I love it. It will be my lap top replacement once I find the right keyboard setup.
My reasons:
They make beautiful products with premium materials.
Over all, apps for their ecosystems tend to be beautiful and unique.
Resale value holds like no other piece of technology.
And... everybody in my circle of friends uses them and I want to be part of the club.
I just got the 15 rMBP and it's amazing. Like it's already been said, it's an incredibly powerful machine for it's size. I was playing Skyrim on it today at 1920x1200 with 8x aa/af with high res texture packs and the frame rate was solid. Really impressed and I would totally get it over the 13.
