Hey! You should know that Canon has released a newer version of this product: the Canon PowerShot ELPH 190 IS.
Adding another $30 to Canon's most basic 2015 model gets you a better zoom, but not a whole lot else. Introduced at the Consumer Electronics Show, the 170 is a basic, yet portable camera.
The 12x zoom allows the small 170 to get up close, and it's a decent feature for the price point. The image stabilization system will help keep shots steady too. Outside of the extra zoom, the 170 is very similar to the $120 Canon PowerShot ELPH 160, with a 1/2.3" sensor, slow .8 fps burst mode and solid .4 inch macro focusing. That .8 fps burst mode is rather concern, indicating a pretty slow performance. And while the 170 is very similar to 160, it does have an even shorter battery life.
If $150 is your max, the Canon ELPH 170 is certainly an option, but look at a few other point-and-shoots first--you can find the Nikon Coolpix S6800 for a similar price if you catch a sale, and it has a much better 9.4 fps burst mode.
The Canon PowerShot ELPH 170 is expected out in early February for $149.
