Name: Bamboo Fun
Same chipset as Bamboo AFAIK
Name: CTE-450 [Bamboo Fun]
It seems the last suggested name is a bit inaccurate. Does anybody else have seen another model (!) name for this one? Also, the Bamboo series is normally marketed as "Bamboo XYZ", where "XYZ" is a random world. There is no "4x5" or something like that (whatever the previous poster meant with that).
Name: CTE-450 [Bamboo Fun (small)]
Tablets with the "Bamboo Fun" product name came in multiple sizes. To help people distinguish between the sizes, the box art contained a label like "small". I've added that size information here for the same reason.
