most of them are 13" ultrabooks. for 14", only the Lenovo S410P, Dell Vostro 5470 and Inspiron 14 7000 are 14". however, keep in mind that they are more suitable towards casual games, work and videos. prices are RRP and negotiable.

normally laptops with graphics cards run hotter than those with integrated graphics, due to the heatsinks attached to each other (dual fan solution is different).

the battery life of the UX31A is pretty good. processors with 'U' alphabet at the back of the model number runs on lower voltage, hence they are more power efficient but weaker performance.

another factor is the usage of SSD in the UX31A, rather than spinning mechanical hard drives.

EDIT - among the laptops out there i suggested, i would rather take Dell XPS 13, cheaper and better warranty service.

how bout this?

rm2899 only..

slim but not light weight..

u can consider apple macbook pro 13 also..

Other than the difference in IGPU vs discrete GPU, ProBook 4430s is entry level business laptop, has better thermal design.
