Im so glad manufacturers are finally coming along with high DPI displays. When I entered college in 2004, I ordered a dell laptop with a 15 inch 1920x1200 display. It was unbelievable at the time and would be nice even today. I probably annoyed the hell out of everyone I talked to explaining 'pixels per inch' and all of that, and no one really understood why I was so excited about it.
Now, 8 years later, because of Apple, we are seeing this become a 'thing.' I can't wait to get a MBA with one of these displays in a couple years (or maybe this year )
