I have replaced BigClock with MegaClock. BigClock didn't work properly on the Clié's high-res screen. MegaClock has the same features and more, including world time and moon phases, and has a much slicker interface.
Weasel Reader, a freeware doc reader, has been replaced by HandStory, which adds web clipping, image viewing and MemoPad replacement functionality. I'm using the crippled freeware version, so I haven't been able to try all the features, but it looks like a winner. I think I will register it.
