I just upgraded to OS2008 as well and noticed that it is a lot harder to bring up the full screen keyboard, which bothers me too. Also, the option to adjust how much pressure it takes (which was in OS2007, though I never needed to adjust it) as vanished in 2008. It crossed my mind that it may increase its sensitivity if you uncheck the box to open it with the d-pad (since then the finger tap is the only way to) but my tests from te last few minutes are inconclusive. It may also be possible to change that sensitivity via a .conf file somewhere or with the gconf editor.

I suppose it makes sense that 2008 is a little more finger friendly overall (since the 810's d-pad is under the slider) but less so for text entry (since it has a keyboard).

Personally, though, I've found the browser a litle annoyingly resistant to clicking links with my fingers, too, though.
