which is which? DSLR or Digital camera?

I’ve been eyeing for dslr camera but I’m quite hesitant to buy one because one thing is for sure, my twin sister will use it most of the time. What I like with the slr camera is it great for taking pictures and the quality of the picture is really great if compared to digital camera. Oh well, I’m still thinking about it. If ever I’m going to buy one, I’ll be choosing the D3000 from Nikon for dslr and canon for digital camera. Wish me luck guys! I really hope so I’m gonna make it happen. LOL. That’s all! Bye guys!
