I got the Asus X5DC free with my mobile phone contract back in March. From using it for a bit i can say it isn't that bad since i got it free. But if i had to pay for a laptop, I would definatly look at other options. It does have a fair amount of programs pre loaded and also it does have a decent and fast antivirus software. But it's not the the laptop i would like to use as a entertainment gadget (playing games and watching vids). It is more of a business tool. So if you have a job whch requires you to move about and you need a laptop, this will be perfect for you.
Decent battery life
Nice spaced out keyboard layout
Poor internal speakers
Wifi connection breaks quite often
The processor is not that great - can not multi task without the system freezing/lagging
The screen flickers a lot.
So to sum it all up. I don't mind using it but if i had to buy it or gift it. It would not be on the top of my list. It lacks a lot of features. There are far more better laptops with superier CPU and RAM. So this is not for me but i am not complaining as i got it free. :)
