Any Acer Aspire S7 13" 128GB model aowner?

The Acer Aspire S7 seems to be the most beautiful Windows 8 ultrabook I've seen. The best part, the screen is 1080p. All the rest of 768p ultrabooks look blurry once you see this beauty. Anybody have one already? The Microsoft store I went doesn't even have it in stock (despite having at least 5 demo units on the floor). The cheapest model has 128GB SSD (2 x 64GB in RAID 0). Thing is, on the demo units, I check the C drive and Explore said the total storage is only 70 something GB, and there's only 30 something GB free. This is not good if there's only that little space left out of the box. Most reviews, of course, reviewed the more expensive unit, the one with 256GB SSD, so they are not helpful. It would be great to have a real info from a real buyer.

So, the question is, how much free space left on the cheapest model out of the box?

Appreciate if there's somebody that can answer this as this thing looks gorgeous.
