Nokia Lumia 1020 buy or no..?

Nokia Lumia 1020 Indian price RS 50,000 I think we should not buy its so expensive and OS is of windows 8 means less app NO INSTAGRAM... and internal memory 32 no option to expand of memory 

If this mobile would launch by Apple or having Android OS this would be best mobile in world 

If u r mobile having 5,8 or 12 megapixels u can increase megapixels buy buying gadget name SONY X10 very good lens compare to android NFC and iOS 

So Nokia is 99% pick because it's to expensive and because of operating system if you don't mind in os and want best camera phone you have 2 option android bases samsung galaxy camera and windows OS is Nokia Lumia 1020 

ANY QUESTION ANY HELP YOU ALL CAN ....
