Declan currently is not planning to support VGA resolutions but these programs should work fine on SE.
As for the content, I have purchased all three of their Japanese PPC apps (including the dictionary even though a number of freeware options exist) and have been more than pleased with their stuff. The developer runs a user forum and responds pretty readily to questions and problems.
Also this guy is a polyglot app makin' fool... he's got flash cards and tutorial programs for Chinese, French, German, Korean... among others. The programs pay special attention to the needs of western learners of Asian languages teaching the ground rules of phonetic and ideographic characters.
I hope this guy makes money off these because they are quality programs that don't sacrifice a bit of usefulness for polish... and they're pretty polished.
Speaking of freeware dictionaries... I use EBPocket. You can download the PPC and Windows versions
here. There is an English dll file for the PPC version that you can also install so that will convert the menus and dialog boxes. The page is only in Japanese but you can find support on installing it fairly easily. The instructions are pretty intuitive so it's possible (hey, if I can do it...).
Jim Breen offers EBWing (EBPocket is a freeware compatible version) configured versions of kanjidic, edict AND the massive Tanaka corpus of Japanese / English example sentences!!!
