Really, no one has to justify their purchases to strangers.
Like it: Buy it
Don't like it: Don't buy it
I agree with jgmecarter. For toting around getting snap shots of kids or photos for Facebook, it is fine.
Personally, when I want more, I tote around my Nikon D3 and assortment of professional lenses I accumulated during my professional photog days (which have all but passed).
