Both are good cameras, personally I like the Canon, for one thing Canon uses SD memory card, Sony card is proprietary, SONY only. The SD card is universal to many devices, something to consider.
Hi! Im looking for a p&s camera that would fit in a small purse that I could use for occasions when I don't want to carry my older and larger 10x zoom camera. I would like the camera to be used for (besides general shooting) going out with friends, special occasions and concerts. I know p&s cameras are not known for their concert shooting but Im talking about shows were I am in the first few rows and do not need a huge zoom. I would however like at least a 5x optical zoom.
3 cameras I am heavily considering are the Sony WX9, Canon 300HS and the Panasonic Lumix FH-25.
