Hi Brian, interesting because I too perform outdoors wearing polarized sun glasses with an anti reflective coating, and don't experience any visibility problems on my 1st gen. iPad. I also utilize a
Moshi iVisor AG for iPad so wondering if this might be the reason, or if iPad2 's new screen simply doesn't support viewing with polarized sunglasses. I recommend contacting Apple about this. Either way, I highly recommend purchasing an anti-glare screen protector to reduce reflective glare and increase outdoor viewability. Please report back as this will definitely influence any consideration on my part in upgrading to iPad2.
Brian, btw: I received and accepted your Skype chat invitation so looking forward to chatting with you there. Leave me a message on Skype IM or Skype Voice message to let me know the best times to find you on Skype.
