Mac is not a product. Every computer that Apple sells is called a Mac (short for Macintosh). You have a Macbook Pro (laptop), Mac Mini (desktop but as limited as a laptop if you plan to upgrade), Macbook Air (a really slim and lightweight laptop), iMac (an All-in-one which has the computer hidden behind the beautiful monitor) and in the end a Mac Pro (same as your regular desktop boxes, only a lot prettier, powerful and crazy expensive). You can take a look at all of them here The Apple Store (India) - Welcome to the Apple Store
The prices listed are MRPs and you'll most probably find it in the local market 5-10% cheaper than what they have listed on the website.
