Wow just today I was using (or trying to use) my 13" mbp but the glare covered up half of the screen! Even though there are no windows in the classroom that is located up on the 5th floor, the inclass very bright fluorescent lights drowned out half of my 13" glossy screen. Now I had to make a choice since I only had 1 hour and 10 minutes of battery life left (been on campus for 7 hours since this morning using the 13" off and on). I had to sacrifice battery life so that I can see what I'm doing.. I do love the 13" but times like these I sure miss the anti glare screen! With my previous 17" anti glare, I used to just use it on 1 notch of brightness in ANY light conditions (even outside under the sun especially here in TEXAS). One thing that surprised me was that my friend's 15" Toshiba had a glossy screen as well but the 13" uMBP's screen was twice as glossy!
