If you're looking for a laptop and don't mind buying refurbished, Best Buy has a pretty good deal on a 15.6" Lenovo you might be interested in. Right now, they've got a refurbished Lenovo notebook featuring Intel Core i5-2410M, 6GB RAM, 640GB HD and Win 7 64bit for $469.99. This is a pretty decent price for a laptop with these specifications and should be great for students looking for something more powerful than a netbook.
Although it's refurbished, there's no doubt the laptop comes with some pretty good features. The second generation Intel Core i5 should handle basic tasks with ease along with applications like Photoshop and Lightroom. It's not going to do much for you in terms of gaming but, for the task-oriented group, this is an affordable laptop worthy of looking into.
Best Buy offers free shipping on orders over $20.
