Since you like MBA, just go with it.

Run bootcamp to run Win OS.

1. Huh? 
2. BS. Totally idle, maybe.
3. Well designed, yes. Best performance - what criteria?

S7 is also on SSD lah, where do you see it has normal HDD?

All the models you listed are ultrabook that run on SSD (which help them to achieve good battery running time).

The thing is you want 13" or below, and want good battery running time.
Want good battery running time, go with ULV CPU. Video conversion, Intel Quick Sync already pretty good. Photo editing - unless you do some extensive stuff, Intel HD4000 can handle it (actually CPU could be more important). Multitask a lot - get more RAM (8G or more).

SSD not only improve battery performance, it also generate a lot less heat - another of your criteria.
It also improve the "responsiveness" of laptop very substantially.
HDD is so cheap now, 1 TB external HDD ~ RM250.

iinm, currently, there is no 13" models spec with ULV CPU & 750GB/1TB HDD. Biggest is 500GB.

No, actually some of the listed models are not ultrabook, there are just light enough, and has HDD as you request.
Ultrabook need to be able to boot up quickly. For Haswell, to recover from hibernation, < 3 sec. Without SSD, that kind of target is just not possible.

If u finally decided SSD , asus zenbook and samsung series 7 ultra would be a nice option , Both fitted ur criteria wanted .

personally i dun use mac air    unless ur work reli need their OS (like some engineering or drawing software) , otherwise stick to Windows as u can get conventional programme easier and more options =)

And also lower price for same specs  build actually price count into their build quality , so u can see around this kind of price in zenbook and samsung ultrabook coz they both uses same top notch build quality , screen in Samsung and Zenbook would easily blew mac air off 

Coming back to the MBA that I mentioned earlier eh?  brows.gif

Good stuff. If you want best battery running time, this is the ONE right now.
Haswell, spec with HD5000 (best IGPU for ultrabook without discrete GPU). The SSD also is the fastest in the market right now (proprietary but very similar to m.2 port)
Within your budget.
As I mentioned, if you need win OS, just run bootcamp (it is fully supported by Apple).

One of the flaw in which the screen is not matte and low resolution . Also , too simple design    forgive me to say so , they just use the same design every year .
