The screens in Mac laptops aren’t as good as they could be; even the iPad has a superior IPS panel. I noticed a funny thing a while back; my current laptop is a 2010 MBP13 [available only in a gloss screen], and I have noticed it has crappy angles of view (particularly up and down). Whereas my ancient matte 15" MBP 1.83 CD allows a larger range of movement before brightness, colour and contrast change markedly. I cannot believe that the newer panels are inferior, so put it down to the matte coating.
Do you know anyone with a matte screen, or can you find one in a store? My 21.5 iMac’s screen is also shiny, but much better than the 13".
Or you could always budget for a decent external monitor; if your eyes are going the way mine are (I’m 59), they will thank you!
