Why do you need the laptop for??
You can get a HP with dual core1.6G with 2GB RAM, mic+webcam and a DVD writer for 700$.
Why do you want to invest 1000$ more over something which gets outclassed in another 6 months??
Me and my friend bought a lappie each just 2 weeks back.
First one is an HP compaq dual core, 1GB RAM and 160GB Hard drive with inbuilt mic for $449.
Second one my friend got a good deal on account of thanksgiving day.
Its a Toshiba...same config for $299
Both of them working really well
