Context: "How to become rich even if nobody is following you on twitter" (http://news.ycombinator.com/item?id=1107828) - my "1$ a day" app now "...one of the most useful applications you've ever installed on your iPhone."
Yep. Or Windows Mobile (shudder). They all got in-page search. How that got left out of the Safari design is beyond me.
The other thing that got left out is the ability to scroll to the bottom of the page - there is scroll to top, but no scroll to bottom (a real problem on long pages - it may be practically impossible to flick your way to the bottom of a long page). So, I made another app - "End Of Page" - this one's totally free and hits the App Store on Friday (Apple willing, of course).
