Laptop sleeve. Good idea?

Hey all. So I'm thinking about getting a sleeve for my laptop. It's a PC, but I've got a question about it.. and we're all computer users here.

Last night my laptop's lid got way scratched up. Some of the silver paint was gouged out and you can see the silver metal that's the top of the lid/screen. I'm trying to prevent any more accidental damage to this machine, but do sleeves do any real good at preventing physical damage, or are they just more for cosmetics (where I'm already screwed)?

so basically.. is a sleeve in any way useful if my laptop's already pretty scratched up?

 

Well, since you asked... and no one knows who I really am.. *shifty eyes*

I was in my friends dorm room doing work, and there's a space between the mattress and wall that's a perfect fit for my laptop, so I usually stash it there after I'm done using it until I go back to my dorm... the rubber grips on the bottom must have clung to the mattress, and the mattress must have somehow started going back and forth, scraping the lid against the cinderblock.

honestly, I'm not even phased because it's a 3 year old laptop and like a year ago it was going for like $500 brand new. I haven't ever seen one go for over $200 used lately, and that's one in good condition (which mind wasn't even before this accident).

I was just wondering, would a sleeve help prevent any other damage that it might end up with, but it seems unlikely as sleeves only do cosmetics.. so yeah. thanks everyone.
