Picked it up the other day. Nice little beastie.
Darn near as fun as a Leitz rangefinder, but at just a little bigger than a Minox... The AE modes work pretty well, and the "ISO" setting will go up to 1600. I've blown up a few shots, and it's nice and sharp. Fast trigger too - if you have the focus light and redeye stuff turned off, there's no fiddle farting around while the thing figures out what it's doing - it just focuses and shoots.
Dunno about battery use - first set lasted maybe 50 shots, but they were the ones in the box.
Haven't opened the manual or installed the software yet. Just stuck the SD in the confuser and used Photochop.
IMHO, an excellent backup for someone who uses a real camera on the job, or a nice family camera.
Also has a macro feature that I've been experimenting with.
