I ask this in all seriousness...not try to start a flamewar...
Why would you install Windows? Is there a video game you play that isn't available on OS X? Follow on question...why Windows 8.1?
No games. I hate osx but there just is not any quality 100% rgb ips laptops out right now that i can find. Any suggestions and i would be glad to return it. 8.1 because it works great for me and is the best version of windows to handle the hi dpi scaling not as good as mavericks but good enough.
Since you hate OSX, you should take a look at Sony Viao Pro 13", the Samsung ATIV Book 8 or 9, and possibly the Asus N550JV or Zenbooks. Some can be configured to have high pixel density touch screen IPS LED monitors with the current Haswell processors, SSD, with integrate or dedicated graphics.
But if you must really insist on a Mac, be wary as the new entry level 15" Macbook Pro Retina DOES NOT HAVE DEDICATED GRAPHICS. Primary difference between the top spec 13" MBP Retina vs the entry level MBP Retina are in the screen size/resolution, processor, size and weight. The integrated Iris Pro graphics in both machines show negligible difference in performance.
As for heat, I have a 2011 15" MBP with a 2 GHZ quard core i7 and replaced it with the top spec 15" MBP Retina with the 2.6 GHZ core i7 haswell. According to my SystemPal app, the CPUs in both computers still exceed 190 degrees F while conducting the same tasks (extensive photoshop, final cut rendering, and running Win 7 via Parallels). The fans in the MBP Retina are noticeably quieter than my old model but they stay on for the same amount of time.
Ok here is why.
Sony vaio pro 13 and duo 13 have good screens but major wifi issues and cost on the larger specked ones is the same as the 13" pro or base 15 mbpr. At least the mac retains the resale for when a windows machine surfaces with my needs.
Asus ux51 small rgb color space and same high cost
Samsung ativ 9 and yoga 2 both have a. Yellow and green issue
Asus zenbook ux301 is not out but is an option
Otherwise I have not been able to find a decent screen and form factor in the $1500-$1900 range. I do hope sony's vaio flip 13 has the wifi fixed since it seems like an option and the sony's have good rgb screens.
Yeah the 15" still has heat but better battery life. Still struggling with wifi connectivity so may swap it for the 13 till something better gets released toward thee nd of the year or early next.
