I'm using it for my study and it's really nice to have this one,because suitable for me as a student.I have upgraded the RAM to 1 GB.

Conclusion
i think this one is quite expensive,because you can get another pc or laptop with the same price.But from my experience after using it for almost 2 years it its worth to buy.
