My wife and I used to have a ginormous 17" HP (a DV9000) - nice machine, but it was HUGE. To me, weight wasn't the issue; yeah, it was a little thick, but that wasn't it either. It was just so darned huge you couldn't put it ANYWHERE. Just pulling it out of the bag was a chore - I had to look and make sure I had clearance all around so I wouldn't bang it on anything (I drive a school bus, so I'm used to checking mirrors and clearance, but doing that with my laptop was ridiculous)! Sold it when my wife switched to a Mac - I, personally, would love to always have a 13/14" laptop (perfect size, IMHO; love my 13" MBP), but since Apple likes to make screen size and performance upgrades go hand-in-hand, I guess I'll have to get a 15" someday. 🙂
