I was home watching the Keynote from today's WWDC on the Apple site with my 15" MBP, (2.66ghz '09 version). My wife came home and started watching the Keynote on the 1.8ghz/128ssd MacBook Air ... what a difference! I've never compared the two side by side during video playback but the MBA was noticeably worse. The text on the screen was chunky/pixelated/blurry and not near as pleasing to view as it was on the MBP. My question is why? Is it just the resolution difference, and/or the 1.8 to 2.66ghz difference, or the ram? If I was shopping today, that in itself would make me at least look at the new 13" MBP in hopes video playback would be smoother and clearer?
