Got a Z1000 myself, which I tend to carry with me most of the time.
Very easy to use, but can also be manually controlled for some effective shots.
The movie mode I find is okay (not up to a true video camera but then it's not one).
The only issue I find is that the flash takes a long time to charge and you can miss shots because of it.
Easy shooting modes
Can display/setup most key parameters from the "right hand menu" (can't think of a better way of describing it).
Shares the same batteys as my 600Pro
flash seems slow to charge
10M means noise at higher isos
i had a casio ex-z50 just over a year ago, the photos where ok in normal light, but in low light pretty dismal, a friend of mine has that sony you mentioned and if i had to pick one out of those two, i would choose the sony.
