Be careful: many
point-and-shoot cameras have both optical and digital zoom.
While small digital
point-and-shoot cameras may not have as many features as their high-end DSLR cousins, such as 16-bit RAW format capacity, noise reduction, and long-exposure modes, they enjoy some highly desirable features unavailable in DSLRs.
If you're already carrying a smartphone, there are many
point-and-shoot cameras and consumer DSLRs with built-in Wi-Fi that can send pictures to your phone.
The buttons are placed exactly the same way they are in almost every single Canon
point-and-shoot camera, so if you've ever used one of Canon's cameras, you'd know almost immediately where everything is.
I'm not sure whether the Samsung Galaxy Camera will be a best seller - it's a lot of expensive tech for a
point-and-shoot camera category where people are used to prices under $300.
