Because I don't understand:

1. CDC isn't for java mobiles but only for PDA's?
2. Pocked PCs can run CDC programs?
3. CDC has a different API from CLDC?
4. What is the difference at all from CLDC?

It assumes rather more compute power on the device than CLDC; but most
current devices which support Java at all are powerful enough for CDC.

> 2. Pocked PCs can run CDC programs?

Yes, with the IBM j9 or Insignia Jeode JVMs. J9 is available in
either 'Personal Profile' (CDC) or 'Mobile Information Device Profile'
(CLDC) variants; probably Jeode is as well. However Jeode seems to be
available only to OEMs, whereas j9 is available retail (and really cheap,
too - about US$6).

> 3. CDC has a different API from CLDC?

Yes; CLDC lacks many features from J2SE, whereas CDC lacks only a few.
