I love the new computer but am wondering if others are experiencing a dimmer screen than the last issue MBP, (in this case, the most recent 13" MBP before this month's update). Also, to get full brightness I have to tilt my screen way back. Any other viewing angle is off. In other words, the optimal viewing angle is when the screen is tilted back fully, which seems odd, rather than somewhere in the middle. Lastly, there's a slight grayish cast in the lower left hand corner as though not as fully backlit. I don't think these things are reason for a return but was wondering if anyone else noticed this on their rMBPs?
