Multimedia Laptop for Home Use - Research for future purchase

[Updated] Multimedia Laptop for Home Use

I have a HP DV6602 AU which was bought almost 5 yrs ago. I want to replace that laptop with a new one.
Link for that thread

I will be buying the laptop two months later in next 15-20 days.. I created this thread early as I need to do research on the products and then shortlist them and based on the price I need to save money. I was thinking about Mac Book previously, but I think its a overkill for the use and my dad would hate OS X .. so going for a smaller budget.

1) What is your budget? (INR or USD)
Rs. 35,000-50,000 (flexible)

2) What size & weight consideration (if any) would you prefer?
Mainstream - 15"

3) Are there any brands that you prefer or any you really don't like?
Best quality required, I would prefer good after sales services and also if there is extended warranty/post warranty AMC etc..
Dont Like: HP ... specially a laptop which looks like this HP Pavilion G6-2005AX

4) What are the primary tasks will you be performing with this notebook?
Home Use: used by family members For surfing, watching videos/online, Music(primary - iTunes), casual gaming(I already have a good enough system to play mainstream games)

5) What screen resolution(s) & type (glossy/matte) would you prefer?
I think 1366 x 768 is the standard for 15" screen. Matte preferred but can settle for Glossy if hardware is good.

6) Anything else you would like to say? (eg: local purchase, ASS,matte/glossy finish)
Will check prices online as well as in SP Road Bangalore, ill go for which ever is cheap.
I will also check Other retailers like Chrome, eZone etc.

the laptop use
95% of the time its home use only.

Dad - iTunes(including CD Ripping), Youtube, Movies, Surfing, Excel - I haven't seen him do anything else other than these.
Brother - Internet Banking, Surfing, Games - Flash mostly. (may be some popcap kinda games)
Sis-In-Law - Surfing, Movies
Me- Troubleshooting in case anything goes wrong

I prefer Intel due to the bad performance issue I faced with my current laptop(AMD), but I am completely open for AMD solution too.
I feel 3rd gen Core i3 would be sufficient, but if Core i5 Comes into the budget then ill be happy
4GB RAM , 500GB/s] 1TB HDD, DVD Drive
Win 7 Home Premium need and also to be included in the budget.. can add 2-3K if total cost exceeds 40K..

EDIT: Update. My laptops Audio has failed. so I spoke to my dad and he said lets go for a new one.

Initially I was planing to buy the laptop but my dad said he will pay . so I can add additional 10-15K to the budget from my end.

His requirement - Should be Fast and Loads of Space
