Music Keyboard Help: Anyone here that can help me choose between Yamaha E463 and Yamaha PSR I500

I'm a total newbie so I have no idea what to expect. There are a lot of videos on E463 on youtube but none for PSR I500.

From what I understand, the I500 has more Indian instrument sounds. But apart from that I know nothing. What does the E463 have that the I500 does not? What features will I miss out on if I pick one or the other.
The I500 is a little more expensive, so if it has "everything" that the E463 has, then its a no brainer for me.

Any tips and pointers will be appreciated. Thanks a lot.
