13" for me

.
While still within the return period of my base 13", I decided to try out the 11" in order not to have any regrets later. I have always eyed it ever since the first model came out: I love the idea of having a fully capable computer in such a small, gorgeous-looking package.
Playing with it in the Apple Store wasn't enough to get a good feel for the screen size and resolution in my daily use, and obviously, doesn't give any indication regarding actual battery life during that use.
Like everybody says in forums and reviews, the 11" is amazingly small (and cute), powerful, sturdy, has a comfortable full-sized keyboard and almost full-sized trackpad. It definitely lived up to all my expectations. It breathes perfection.
But... I prefer the 13" for two reasons:
1.
Battery life: (tested on an i7 / 4 GB / 256 GB) Starting from 78% of remaining charge out of the box, it lasted almost 3 hours of web browsing, HTML5 and Flash videos, 720p videos. Playing a low-bandwidth (3.5 mbps) 720p video in VLC over Wi-Fi, a full charge would last 3h57, while playing a high-bandwidth one (10 mbps), it would last only 2h50. In the same tests, the 13" lasts about one more hour.
2.
Screen resolution: The size is fine, though I keep wishing they would expand the screen over the currently large bezel. The 16:9 aspect ratio is perfect for me: movies and TV shows expand over whole area (that's why 11" is fine). The pixel density is not as impressive as in the 13" (even though it's higher) simply because there are less pixels in total. Videos are not as sharp, text and images are more pixelated since they're rendered with less pixels. Also, text is just that little bit too small. After using the 11" for 3 hours, I went back to the 13" and the screen felt huge in comparison (in a good way). The bigger screen surface felt liberating, and text and images were crisper. That was the deciding factor.
I could live with the shorter battery life. The screen size is enough given the 16:9 aspect ratio. It came down to the difference in screen resolutions. Both the 11" and 13" feel equally as comfortable to carry, move around and use on my lap. As a consequence, the lower screen resolution, while impressive for a computer that size, is a compromise that I can't justify making. Though I could definitely use the 11" as my main computer, the 13" being better in the two areas listed above, it's the one I'm going to keep
