A few more observations.....
I just fell in love with the 700

The 700 is much crisper at night than the 505 w/ACL1. The ACL1 has a haze or frosting on the glass. The 700 is much sharper at night. I prefer the 505 during the daytime and the 700 at night. The 700 light seemed less stressful than the ACL1 cover.....almost soothing.
The 700 reminds me of that Seinfeld episode where the girlfriend looked different in different lighting. 700 is great at night and avergage during the daytime.
The touch screen works excellent with absolutly no problems with finger prints. The little black flash is still visible when turning a page
