I have it installed and it seems to work really well.
However, I noticed something peculiar... I used to frequently go to the NYTimes website on my LG Lotus. When I visit that website on my HTC Hero, the display layout isn't the same. On my Lotus it showed up in "newsprint" format. A little more unwieldy to navigate, but I didn't mind as I like looking at something that resembles a newspaper. With the larger Hero screen, I was looking forward to that even more... but it doesn't show up that way. It's in some spartan linear layout. Even some parts don't show up right, like weather forecasts--data doesn't appear under columns, so it's all askew.
I checked the Opera settings and couldn't find anything to affect this. Anybody have any ideas?
