I would recommend you to buy the Asus K42JA VX048D Laptop which comes with the following configuration:
Processor: Intel Core i3 370M (2.4GHz), Display: 14" HD Glare, RAM: 2GB DDR3, HDD: 500GB, Optical Drive: DVD RW 8X SM DL, Graphics Card: ATI HD5730 2GB DDR3, WiFi: 802.11 b/g/n, In-built Webcam: 0.3M, Bluetooth: Bluetooth 2.0, Battery: 6Cell, Operating system installed: DOS
If you want the best specs for the buck then get the asus K42JA but if you want the best after sales service then customise a dell inspiron as following: i3@2.4Ghz+3gb ram+320gb HDD+Ati 5470+targus backpack@37k+1k shipping,this spec is sufficient for your usage conditions and you will also save some money.Here is the link,customise the third model from left:
