Look through the reviews section... You'll find answers you're looking for.
Also, look at the NUMEROUS posts over the past 2 days. This topic has been the focus of discussion about non-stop. And no matter what it comes down to, is the extra inch worth $299 (especially since hte 16" is less quality than the 15") , Personal Preference.... You know what you want, in your mind, you already know what you're getting, so just go for it!
Also the 2-3 week wait for a 16" screen, if you don't mind waiting the extra time, + spending the extra $300, then do it..

Is the "official" review of the 8890.. I wasn't able to find a picture of the 15" screen in a 8890, but I can't imagine it would look "THAT" horrible.
