Not all laptops have glossy screens. And why are there glossy screens in laptops? Well, they are usually low'ish-end consumer-laptops. When consumers see those glossy screens, they think "ooooh, shiny", and they buy it. But that doesn't mean that it's actually better.
There's a reason why MacBook has a glossy screen, whereas MacBook Pro only offers it as a BTO-option.
IMHO, I think glossy screens are here to stay. It wasn't too long ago that people thought widescreen TV's and monitors etc were just a novelty. Glossy screens make your images pop. True, that might not be as realistic but remember the old slide film projector days? You can't get a glossy print to look anything as good as the slides shown on your projector in a dark room. Sure, maybe a Cibachrome print viewed under museum lighting ...
My point is, who's your audience? I can understand that if you do your own digital printing (ie, at your desk and not sending off to lab) then you want the print to look most like your display - matte is probably better. But, even with my hardware color-calibrated display, I can't control how it prints at the various consumer to pro labs I use - even after soft-proofing with profiles in PS CS2. You never know who the operator is at the other end and whether their machine was calibrated that day before printing.
If you're selling prints, what's the chance the buyer will be inspecting your print under a 6500K calibrated OTT light rather than incandescent or fluorescent lighting conditions.
If you're putting photos on the web, how many viewers have profile aware web browsers and hardware calibrated monitors?
I own a matte external monitor but prefer my glossy laptop for the simple reason that I enjoy the images more on my glossy screen ... the same way I used to enjoy a slide projector show ... but now I'm dating myself
Oh, and as for glare, I can usually tilt my screen enough to avoid overhead lights and after a while your eyes tune it out as you adjust.
