Macbook 13
Pros :
1. OS is great and resistant to virus attacks etc
2. Great battery life
3. Sleek looking with great features like thunderbolt
Cons :
1. Macbooks not very popular in India, are overpriced
2. No dedicated graphics - Don,t expect to play games
3. 13 inch is smallish display if you consider watching movies
HP Envy 14
The Envy available in India is beats Audio branded. Awesome for Music and Movies. But you'll get even better sound quality and better graphics in XPS
Dell XPS 15z
One of my favorite. Has built in JBL speakers- the best in any notebook so far. Nvidia GeForce GT 540M will cater your gaming needs decently. Great built quality. You wont regret buying one
My laptop HP Pavilion dv6 6017tx
I was going for a XPS 15 earlier but this machine offered a better graphics card so I opted for it.... and I am loving it. Nice battery backup, great screen. Speakers are not as good as XPS but are loud and great (same speakers as in Envy 14).
If you are buying in the US you'll get a free upgrade to 750GB HDD, 6GB RAM and a BluRay drive. Cost will be around ~ $1100 but there is 25% discount coupon also available
If you don,t have any specific need/love with Apple products I would recommend you a XPS 15z or HP dv6. Both are great. You'll love any of them
