After buying a glossy MacBook Pro I won't be going back to matte (on notebooks, anyway) without kicking and screaming.
The gloss has been less than an issue, in fact; if you've ever experienced a matte screen completely blowing out because of one intense reflection or light source, that doesn't happen on the glossy screens. Instead of the coating making things worse, the reflection stays confined and you only lose the part of the screen it's hitting.
I've used my current MBP naked at locations I couldn't have dreamed of using any of my matte laptops without a serious monitor hood.
