Visited Nehru Place market in Delhi today and went to Lenevo, HP and Dell showrooms. Had a look at Lenevo Y510P, HP Envy 15-j109TX and Dell 7537 (Actually saw one model lower than Y510P and 7537 as they were not available). Without talking much about specs, here are quick comments:
Lenevo Y510P: Number keypad area sags when keys are pressed, fingerprints on the laptop body easily seen (though not a major problem), Saw how DVD drive caddy bay can be replaced, was told that it can be replaced with HDD or Graphics Card or Cooling, Best price 72500/-
HP j109TX: Finding it hard to use the mouse pad (deal breaker for me), Looks really good / sleek, DFG keypad area sags (don't like that), Best price 78800/- Touch, 69000/- Non-Touch + Free DVW+Goodies
Dell 7537: Looked good to me, solid & I liked it, i7-4500U

, Best price: 80000/-with bag
Update:
- One downside with Y510P: It has only 1 USB 3.0 SuperSpeed, 2 USB 2.0 (one always on). Others have total 4 with 2 2.0 and 2 3.0. This would be a limitation, isn't it?
- Any idea on fan noise on Y510P and other models?
- Any idea on how Y510P's battery area heats up on usage? (my current old HP laptop has both these problems).
- Y510P comes with Windows 8. I surely wanted upgrade to Windows 8.1. Can this be done on my own and free?
