yes, laptops begin increasing included RAM size as a standard. Now some laptops have 4GB of RAM, expandable to 8GB. But, the price is also higher.
what would u use laptop for? including gaming?
If you're only doing programming, writing stuffs, and such, 2GB is fine. But if you do multimedia, graphic design/rendering, AutoCAD, then at least 4GB. If you game heavy games, such as Starcraft II, 4GB is required.
