I just bought a UX21A here in Hong Kong. They have had them for a few weeks now here.
11.6 FHD IPS Matte LED 1920 x 1080 (AMAZING!)
6 Cell 4800
I7 Ivy Bridge CPU
4GB DDR3 RAM
Win 7 ($15 upgrade to Windows 8 when it's released)
2 year worldwide warranty.
I've had it one day now and so far I have no issues with WIFI. The keyboard is nice to type on. The trackpad takes a little tweaking but is no way as bad as people say. The screen is sooooo good with the matte finish and IPS. Again the sizing DPI needs some tweaking but it's worth it...I've never seen colours look so rich and I'm looking at the web world in a whole new light.
It boots in around 5 seconds. Battery life at the moment is around 5h 58mins. The screen does have a tendency to drop back a little when fully maxed out but it's not an annoyance.
Cost me 11750 HK$ which translates to GBP £968 or US $1514
Again..that screeen is awesome...sorry Mac Air but what I look at when I'm doing my stuff is important to me more than anything so have to see..your airs you don't compete.
