I also was reluctant to make the move to 10.04 as I thought I had a pretty stable 8.10 install functioning.
10.04 is clean! For me personally there was nothing working under 8.10 that did not function in 10.04. What I actually found is that new devices, templates, etc functioned better after I moved to 10.04. As I have seen your input on these forums going back a long ways I know you are familiar with lmce and should not have a problem getting any of your 8.10 configured devices up and going with 10.04
