I have a rooted Desire with a vanilla Sense ROM. Like most Desire owners, internal memory is always an issue. I recently created a 512 MB ext partition and installed Link2SD (from the market) to move my apps over. Up until now, Link2SD would move the app and Dalvik cache, which was great and freed up a lot of space. But it wouldn't move the library file, which in the case of space hogs like Adobe Flash and Air, was actually the largest part. Well, as of the most recent update, Link2SD now moves the library files too. So you can now move almost the complete app over to your SD card IMO this is a great solution for rooted users that don't want to play around with custom ROMs. And the program has a pretty good interface too, showing you the exact amount of space taken up by the app, Dalvik, and library for each individual program. You can then choose which bits of each app you want to move over.
