I've just got the MJU 800...not the smallest of cameras but still pocket sized.
The zoom isn't great but comparable with other cameras of this size. The digital zoom as with other cameras isn't worth toffee.
The build quality is good...although weather proof case. Massive screen, not too heavy. The video function is good, and picks up the sound very well with very little background noise.
The food being XD cards are a little bit more expensive than most £55 for a 1gb click here go for the olympus and you get the panaramic function.
Not used the Minolta but other ones I've seen seem fine. The sites below may have some reviews.
