freddy: 4gb ram should work fine for most things most ppl do. unless u are doing a lot of 3d video rendering and stuff.
mindsg: it has surfaced on amazon for ux21, you can go take a look. and on other websites like xoptic. i emailed them asking about the difference and one of their rep said this:
"The only real difference in those two difference ASUS UX31 models, is the XH51 version comes with the Windows Professional Operating System. The DH52 comes with Windows Home Premium. Is actually a cheaper model when you got with the DH52 and upgrade to the Windows Pro if you wanted that.
As far as the parts go, we cannot guarantee the brand names. It is truly up to the manufacturers and what is available at the time of build."
but i still get the feeling that maybe the later batches are more stable with earlier problems fixed. but then again, i m guessing that it is also possible to live with the older model as other ppl who have posted in this forum have stopped posting, so well, no news is usually good news.
it has been said that a whole new range of ultrabooks are going to be unveiled in CES 2012, but by the time it hits the market, it will be like more than 6 mths from now i guess. unless u want to wait ... which i dont think i want.
