Seems to be more of a competitor to the HX100V with similar body types. I love being able to just put the HX9V in my pocket, or in my cup holder and whip it out when needed. The FZ150 would require me to carry it around my neck like my 60D. Not saying that is bad.
I agree completely. Pocketable is very important to me. That doens't mean there isn't a place for this other form factor that is larger (but smaller than a DSLR). I LOVED my FZ35, the IS was STUPID GOOD. Especially zoomed all the way in. HX9 is better when walking though.
