Yeah, I was a bit worried at first when I got my Mid-2011 MacBook Pro (first machine I'd got with a glossy display) but it turned out to be fine - I've never really had any issues with it. If there's glare, usually you just tilt it slightly and it's fine... And it really does make a big improvement to colour saturation.
Improvement? For watching movies maybe, or a vacation slide show. But for working with color, I haven't found a better option than a well calibrated matte display on the mid-2012 MBP.
