rolf wroteI bought myself an Acer Aspire 5733 about 3 months ago, at $400. I belive they reduced the price a little now.
15" LCD, the CPU is intel i3 M380 @ 2.54Ghz. Not very powerful but much better than Celeron or Atom and well enough for all things except gaming. HD is 320 G I think... (I am not sure because I replaced it with an SSD as soon as I bought it).
It's rather light. The build materials are not great (feels like cheap plastic) but acceptable. The LCD image quality is also not great but acceptable. The mousepad is a bit too small for my taste. The variant I bought comes with Linux installed, and 4GB RAM.
Battery life is not great either. Maximum 4 hours. With windows 7, expect around 2 hours usage. But you can buy aftermarket batteries with double capacity, and they don't cost too much... yet I don't know if you can find them in lebanon.
I still recommend it.
I got mine from compuworld. You can buy it from pcandparts.com too.
From your description, I guess it's the same laptop I have at work. I have Windows 7, Visual Studio 2012, Office 2010 and SQL Server 2008 installed on it. Never had issues with it so far, pretty good laptop for such a cheap price. One thing though, is that mine has been upgraded to 6GB of RAM so I am not sure how much a difference that would make.
I also recommend it.
