It is one of the best entry level dSLR cameras at present.
Its sensor performs as well as the Nikon D7000 and better than any of the Canon APS-C sensored cameras.

It depends on who you ask. It has no ISO button on the camera, no AF motor, which is what I don't like about it, but it's still a great camera.
Since you already bought it, don't worry about things like that, just go out and shoot, read tips etc.
