Don't know which way to go... New camera choices

I don't know, for less than the price of the RX100 you can get a NEX-5n, more camera and only a little larger.

RX100 4"x2.3"x1.4" 8.5oz. $650.00

20mp 1" sensor 13.2mm x 8.8mm

non interchangeable lens

NEX-5n 4.4"x2.32"x1.5" $500.00 with kit lens, ($400.00 body only)

new 16/50 compact lens 13/16" ($350.00)

18/55 kit lens 2-1/4"

16.2 oz with kit lens

13.5 oz with 16/50 compact lens

16mp C sensor 23.4mm x 15.6mm (less mp, but 3x larger sensor)

tilt touch screen, remote capable, interchangeable lens

buy it with the kit lens then when the 16/50 comes out in Jan, sell the kit lens for $150 and get the 16/50.
