Is Apple Not Selling Regular Mac Notebooks Anymore?

So did Apple discontinue selling Mac Notebooks? I hope not. I was recently on Apple's website and I seen under MacBooks, the regular NoteBook laptop wasn't available for purchase. They only had the MacBook Air and MacBook Pro laptops to sell. I'm really not a fan of the sleek MacBook Air look, it's ridiculously too thin. I just want to know, are they discontinuing Mac Notebooks or just holding it off for a while? If you know anything please let me know. I really would like to know the BIG difference between the MacBook Air and the Mac Notebook. If you know anything please give me a heads up.
