$359.99 for Lenovo G570 + $10 Shipping
This is the cheapest G570 I could find on the web as of today because the same unit goes for $399 AFTER the cashback over at MSY. It comes with Intel i3 and has full range of specs perfect for casual office or home use. I think the price is certainly reasonable for the quality of Lenovo laptops so I'm buying one right now, especially since it already comes with Windows 7 Home Premium. This will obviously be performing great considering my needs. It weighs about 2.6kg with the battery so it's fairly light if I want to shuffle it to and from the office.
