I play games but I'm not a hardcore gamer (no crysis and such)
I want my laptop to last at least 3 years.

Spec wise Asus is the best because of the GTX260M but I'm worried about the heat problem (and how this might affect the life span) and also the laptop cover (with blue gaming logo stuff, it might not look very professional)

I never had experience with Dell or Sony, so I'm not sure what to expect in terms of build quality, customer service

Any kind of info or opinion would be greatly appreciated thanks.

 

Get Asus. I hate sony and hp

 

sony is overpriced as always. buy the xps.

 

Definitely go with either the asus or Dell. I, for one, will likely never own a Sony laptop.

My wife has a studio xps 1640 and I like it quite a bit. I was thinking about getting one for myself but decided I didn't want to wait for a month and really wanted a laptop with the i7 and gtx 260m gpu...so I went with the asus g51j a1. Plus the asus I got is a bit cheaper than the studio xps 1645.

 

Thank you for the replies.
I will listen to more opinion until tomorrow

 

Also to clarify more

This laptop would be my moving desktop (since I'm not planning to have one)

That doesn't mean I want anything more than 16".

My screen size is set at 15"~16", because I think this satisfies my need for portability(17"+ is just too big for me)
and also good enough for my main purpose (computer programming. reason why I don't go for laptops with 1377*700 resolution laptops. It's just too small to have multiple windows open for coding)

I do game a bit (this is my only gadget to play game on since I don't own desktop or gaming consoles) what I meant by casual gaming is that I don't expect my new laptop to play everything on high resolution with high FPS.
I want something that will be able to play new games that comes out in next year or two at mid settings (is that impossible with the 3 I listed up there?)
