No Built-in Viewfinder
In the lack of a a viewfinder, holding the camera away from the body while using live view is not very stable, especially with heavy camera bodies and lenses. Besides, LCD screens are very hard to read under bright sunlight. Slow Lens at Wide: f3.60
An articulated screen gives you the flexibility to shoot in non traditional positions such as waist level, which helps you to be more creative and unobtrusive in the streets. No RAW shooting capability
Wideangle is used more common then the tele angle in street photography. A larger aperture will give you extra shutter speed without boosting the ISO in order to reduce blur in low light conditions which is a common scene in street photography. Small 1/2.3" (6.17 x 4.55 mm) sensor
JPEG files are generally more attractive direct out of the camera but RAW files contains much more color information compared to JPEGs, and gives you more room for post processing without significant quality loss. They provide wider dynamic range and option to recover shadow and highlight clipping to some degree.
