Megapixels don't really mean squat.
To a extent.
My two cents. Not that my opinion is worth that at all. DSLR all the way. This will enable you to "grow" with your interest in photography, if you so choose.
What kind of DSLR? Depends what type of photography you are going to be doing. If you are taking general pictures is all, go cheap(er). If you are looking at action or "high end" photography. Quite frankly you get what you pay for. Another opinion. Your camera is only as good as your glass (lense). Put a crappy lense on a very high dollar camera and you will be disappointed.
I started with a Nikon D70. Not too bad for back in the day. But, damn it was terrible in low lighting and had too much noise about ISO800.
Upgraded to a D7000. Couldn't be happier.
