Hi Pros, pls help to suggest a good buy for me for my requirement as below:

1. I need a laptop that will dissipate less heat most importantly at the palm rest and preferrably at the bottom. I kinda need to place the lappy on my legs for typing quite frequently and hope my legs won't get burnt. I have a hp tx2520 laptop with a Athlon X2 processor, i juz can't put it on my leg for > than 1 min as it is so hot that it could fry an egg!!! (Even when i'm juz surfing, not playing games) I hope this wud not happen at my new laptop.

2. With GREAT battery life, best possible based on u all experience, as I know the no. of hrs in the advertisements r not trustworthy. Expectation will be at least sustain a 4 hrs of continuous use for net surfing.

3. Nothing with a intel HD 3000 or GMA graphic ONLY (no discrete graphic, i mean...) and at least 4GB RAM.

4. Lightest possible but of course not as light as an ultrabook as I have limited budget. (preferably around 2k, max 2.3k. Will buy a 2.3k 1 unless it's really damn good deal)

My priority will be in the follow sequence: Less Heat -> Battery Life -> Specs as specified -> weigh
Btw, is there any laptop with i5 Ivy bridge CPU, no discrete graphic (as HD4000 built in), at least 4GB ram in the market currently with a good price?

But we are unsure of the iGPU though...
