SCORE! I've managed to piss someone off enough to deconstruct every sentence of my post!
Those borders are too big, that's my opinion, you posted a mock up, i critiqued it, that's life, deal.
I take care of my things too, I believe one should always have a laptop in a sleeve and in a bag when not in use. But you got to admit, the moron who decided to make a laptop skin out of Alu should be fired. From airport problems, to ease of damage, need i say more.
Hamster powered laptop? Aww is poor baby upset because his little macbook pro can't get more than 3.5 hours out of a full charge. how sad.
Generalization? Check out what this entire forum, hell what every mac forum, the blogosphere, the tech news world, and just about any credible podcast is saying about the heat issues. it's a problem, that needs to be fixed. first step to fixing a problem is admiting it's there. so stop trying to cover up the massive defects that are apperent. a laptop should be comfortable enough to use in your lap, period. without fear of testicular cancer.
And honestly it's your sisters fault she can't use a computer without screwing it up. i'm on the same windows xp install for the past 1.5 years now and i have zero spyware, or malware. i use the best antivirus and antispyware tool on the market, it's called common sense!
As a personal tip, if you want to help out your sister install ubuntu on her machine.
And it's not common sense, it's common stupidity to get into an OS that you'll have to maintain every single day when you have other options.
