PocketLOGGER ZT (cheap display for palm user and zt2)
 

After waiting for so long, it's finally out. They got a version for palm os now, which makes it cheaper for anybody who owns a palm (all you actually need is the cable).
This so cool, cause now you can have a permanent display :D on you car and only use the laptop when tuning.
