I find it interesting that this laptop more or less falls right in between your standard fare laptop and an Eee PC in terms of portability and raw power, but is the most expensive of the crop.
Using the base Vostro 1500 for the "average laptop" and the Eee PC 8G we have:
- Eee PC - 7" display, 800Mhz Celeron, 8G storage, 1GB RAM @ $549
- Wind - 10" display, 1.6Ghz Atom, 80GB storage, 1GB RAM @ $649
- Vostro 1500 - 15.4" display, 1.6Ghz C2D, 120GB storage, 2GB RAM @ $499
I realize the comparison is odd since they all hit different intended markets, but it seems that something that is between the two in specs would be closer to either of the two in terms of price than it currently is.
Compared to the EEE, you are paying for the larger 10" screen & faster processor.
All in all, it makes perfect sense to me the price placement from your list.
