Casio EXILIM EX-Z4u questions

I have a Casio Exilim EX-M2 that uses USB 1.1. It's not all that fast
reading from the camera in the cradle, but I just start the pictures
dumping from the camera to the PC and do something else for a minute or
two if there are a lot of pictures. But if you want to write TO the
camera, it's much slower.

I wouldn't worry about USB 1.1 as far as future compatibility, it should
be supported under the USB standard for quite a while.

If the speed bothered me, I'd just get a card reader as the other poster
mentioned, they're pretty cheap.

I'm happy with my EX-M2. If your relative focuses on the "really small"
part, consider the EX-M20 (the followup to the M2) or EX-S20 (lacks audio
features) instead of the EX-Z4u. The Z4 is about twice as thick as those,
heavier, and slower. Also, as far as I can tell, the Z4 doesn't have a
movie mode, which although limited, I've found to be a fun and useful
feature on my Exilim.

Other really small cameras to consider:
- Casio Exilim Z3
- Canon PowerShot SD10 Digital Elph
- Kyocera Finecam SL300R
