I have slept with my BA inflatable / bag system on the ground and in a hammock. For me the cold clammy feeling of condensation was the same in both situations. That's why I built an underquilt. No more problems. YMMV!

When its cold I use a Ridgerest. I hate sleeping on a pad! Always have a little condensate in the grooves. Not enough to wet my bag. I am going to get an uq.
Another very major point.... on the ground the pad is flat.... You have 5 points in contact with the pad and your body curves away from the pad allowing evaporation, plus as stated your frequent tossing and turning allows the evaporation....
In a hammock with wide pads they wrap up around you and the hammock serves to keep a full body presss of the nonbreathing pad around you...Literally some have experianced actual sweat puddles under the small of the back under these conditions...Evaporation of the sweat is near impossible if you are sleeping warma and are a sweater because of the wrap issue.... It really is quite different from a pad on the ground.

When I got into hanging I picked up a tip from Sgt Rock's site to cover the pad with a piece of fabric to deal with condensation. In my case, I found a lightweight fleece throw at Campmor which more than covered my 40 X 60 pad, weighed 11oz, and cost about $11. Campmor still sells 'em (micro fleece throw, #82223-B).
For a long time I carried that fleece and clipped it to my pad. And it seemed to work...I virtually never had the issue of condensation. But I always begrudged the 13oz (incld clips) which was nearly twice the weight of the pad itself. I eventually stopped using the fleece...and still suffered no condensation problems.
Much of my luck is probably due to my location...I'm in the arid mountain west and humidity, even at night, is not an issue. The rest of my good fortune I attibute to my sleep system. I'm always in Smartwool long underwear (again...mountain west=very cool nights) and that set wicks very nicely.
That might be a starting place for those with pad/condensation problems...try a wicking baselayer.
