1) What kind of problems ?
2) No backlit keyboard
3) No.
4) CB45 has been launched instead of CB35. Its heavy, but you can't compare an unltrabook with regular sized 15"6 notebook.
1.) xps 14z - As per the reviews, there are a lot of wifi issues, plus the build quality is not that good. Do you have any info about that? Other than that this seems like a good enough laptop.
2.) dm4-3022tx has a red backlit keyboard... that's what I read. I wanted to have a look but it's not available anywhere. Which one do you think is better.. xps 14z or dm4-3022tx(beats edition)? the latter is comparatively cheaper too
3.)-
4.)I'm only looking for 14" laptops, coz all the 15.6" ones are too heavy for my liking.
