Nice article… Please tell me about the os. will windows 7 come out of the box for these laptops?
Will all these run windows 8 smoothly once in arrives….
Windows 8 requires
1 GHz or faster processor
1 GB RAM (32-bit) or 2 GB RAM (64-bit)
16 GB available hard disk space (32-bit) or 20 GB (64-bit)
DirectX 9 graphics device with WDDM 1.0 or higher driver
So I dont think there wont be any problem running windows 8 on those laptops
