If you're lucky, then glossy glare will bother you in an airplane.

If you're like me and ..hmm.. pretty much anyone I know, then glossy glare will bother you everywhere and anywhere -- except, perhaps, in total darkness.

Needless to say, if you want something that "uhh, looks pretty", and you don't plan on actually using the laptop for anything other than to look pretty, then glossy may be the thing

If you want a laptop to, you know, play games, watch movies, photos, emails, browse the www or even do work on, then you'll want matte.
