New Laptop: HP Pavilion dm4t

My current laptop is an aging (but still cool!) Panasonic Toughbook T2 that I bought used back in 2007 for my second trip to Thailand.  I've been doing some research for my next laptop.  Some of the criteria are

• ~ $1,000
• Light weight (< 5 lbs)
• Between 13" and 15"
• Intel i3 or better (no C2D)
• Decent battery life (> 4 hours)
• 4GB RAM
• Discrete GPU
• HDMI out
• Webcam

Here's the list of the laptops that I looked at

• Acer Aspire TimelineX AS1830T-3721
• Acer Aspire TimelineX AS4820T-3697
• Alienware M11X
• ASUS U35JC-A
• ASUS U43JC-X1
• HP Pavilion dm4
• Sony Vaio Y Series
• Panasonic Toughbook T7 (used)

After a bunch of online reading (engadget, PCMag, cnet, LaptopMag) and checking it out in person at BestBuy, I found some coupons and went this HP Pavilion dm4t for roughly $1,050 (customized from HP website):
