I am also very happy with OS2007HE. It really didn't take very long to get up and running and I have had only one reboot since running it. It is worth trying if you enter lots of text as the handwriting and thumb board seem more responsive.
It is also mre finger friendly. Speed wise it is also generally better, although I am also now using Fanoush's 48mhz kernel. I find Opera to be just as stable as on 2006 and still a bit better than microb in terms of speed.
Well worth trying as it just feels a lot more polished than 2006 as well as better availablity of apps for bora.
The only app I haven'tt been able to get working so far is acmonitor. I am running gnumeric, mauku, maemo mapper 1.4.7, simple-launcher, quiver, synergy, dropbear

Have fun
