They only had an iMac with it – I assume it’s the same? If so, it’s _mostly_ equivalent, but the glossy screen definitely has deeper contrast, and appears sharper for text, though terminal usage wasn’t quite as pronounced as the browser.
I’m still tempted to buy one to try, and return the one I end up not liking. Most of my usage isn’t in areas prone to glare, but occasionally it is, and it’s annoying. I just don’t want to sacrifice sharpness, because I love how crisp text is on these screens.
The only caveat is the nano texture is much more difficult to keep clean and maintain.
