I've had three laptops in my life, and my progression has gone from a 17" Dell to a 15" HP and now to a 13" MBP. When I first got the MBP I thought the screen was on the small side and was seriously considering going for one of its larger cousins but now after using it for a few months...I really don't think I could go back. It's the perfect size for a portable computer; especially when I'm on the go like in a car, a Motor-home or an airplane. When I use larger laptops now, they just seem so bulky and unwieldy. Now, I can understand why people who do editing or similar work on their mobile computers would need more screen space - but for someone like me who mostly uses my computers as media consuming devices along with some very light word and photo editing, it's just the perfect size. If I seriously wanted more space I'd look into an external display...but 13" is the sweet spot for me now. Just wanted to hear what you guys think is the sweet spot. And well.... Here's a 20 inch Dell for your viewing pleasure...or shall I say, disgust.
