I am using Acer Aspire 4520 from last 2.5 years. Configuration and price is quite competitive. Performance is also good.I can play some of the well know games with inbuilt Nvidia 7000M Graphic card.I observed one major issue (also by some of my friends having it) in its speakers. They output no sound after 1-2 years. Search on the net you will get all the complaints about it. The issue is not resolving by Acer in the newer version of also. I don’t know why they don’t look into that. Almost all the laptop of this series are suffering from it. -KK
