Hum. Looking more closely at TZ60 samples on DP Review, the lens gets a bit smeary in the corners at the widish end, while lawn grass tends to get mushed, probably by a mixture of lens effects and noise reduction. Maybe for some this is an acceptable trade-off with superzooms, but I find it a bit off-putting. My TZ3 was only a 10x with 7 Mp effective, but the lens was much better-behaved and the NR didn't mush things so much. But it used a CCD, which maybe explains things, and didn't have great ISO performance. And phones weren't pushing compact cameras out of the market.
I think that marketing has pushed compact-camera lenses and small-sensor ISO far beyond their optimal performance range, largely because the punters can't tell the difference: witness the rash of crappy supermoon pics on FB.
