I have been testing two i5/8gb ram machines. One has 128gb sad storage and the other 256 ssd. I have Mountain Lion and Windows 7 installed on both. Both the screens and the ssd drives are Samsung. Likes: - Excellent performance. I am getting the same windows experience score as my 2010 quad i5 iMac with 8gb ram and HD5750 1gb ram video card. I doubt that the average person will need more than the basic specs. - Gaming performance in windows is impressive - Screen has a nice contrast and is sharp enough for most people - Sound is loud - Computer is ultra quiet under light and medium load Don't Likes: - Keys are a tad mushy despite being very responsive and easy to type on - Not used to the trackpad yet since sometimes it doesn't register right clicks properly. I might need more time with this. - Drivers for windows are not 100% there yet. Keyboard backlight keeps on resetting to max brightness after every restart and I cannot connect to any wifi networks occasionally. Restarting the system seems to restart the wireless adapter inside the machine which fixes things. - Despite the impressive gaming performance, the machine does get very hot and loud. This necessitates removing the laptop off the lap and onto a table to allow for better air flow. 128GB vs 256GB: - 256 gb ssd definitely has faster write speed (700MB/s vs 400MB/s) - 256 gb machine keep on getting a higher windows experience score (6.7) than the 128 gb machine (5.9) - You can't help but feel that the 256 gb ssd should cost around $100 more than the 128 gb sad, not $200.
