I got my hands on the new supercheap Powershot A590 IS. I might do a small review of it in the coming days.
They've changed the looks of the A590 IS pretty drastically from its predecessor the A570 IS. Some darker and shinier plastic. They've also removed the round button setup on the back in favour of a cross of buttons. The front ring you have to remove to put on a telephoto or wide angle converter is quite annoying to take off.
All in all pretty boring.
The best part of the Camera is the $199 CAD pricetag. This will probably ensure Canon will sell as many as they can produce.
