The screen size is what I use for hours a day and for me fine. You must see each in person to make that judgment.
The dv6-1261sb does run warm. Look at what's in this beast and you see why. It does NOT overheat. But then I tilted the back so the keyboard angle is better for me and that affords some extra air space and flow.
However I think it will be your usual few year laptop in that advances will have me cycle this out in 2 years. If I had the 1250 I would have preferred that as I have no need for the 3d chipset but then we have the upgrade to 7 Pro for which the work I do would have the price go right back to the 1K mark.
Hope this helps and be sure to see both KEYBOARDS as those are not identical.
The 4500MHD graphics surprised me at how many games my kid threw at it.

I have to choose between HP Pavilion dv4-1551dx which has a 14.1" screen and a HP Pavilion dv6-1234nr which has a 15.6" screen. Both have more or less the same specs otherwise and are priced the same too. Which one would you recommend? I have heard that dv4 having a smaller size and weight might have heating issues after a year of purchase or so. Anyone having any experiences with either of the two laptops and could help me?
Thanks!
