What is a fairly cheap, portable, functional pc laptop?

I'm looking for a laptop or something similar (like netbook etc.) that is fast and good for surfing the internet. I mostly would use it for internet- email and websites, watching videos/movies, and microsoft word, no high powered downloads/programs and things. It needs to have a keyboard and be able to have a mouse. I just want a reliable computer that will last a while and is functional and easy to use. It would be nice if it was portable so that its small enough to fit in a backpack but this is not my biggest concern. I am interested in a pc, not a mac. I am looking to spend around 450 dollars or less. Thank you in advance for your feedback!
