$200 laptops can be found but the most of them are only useful for very basic productivity work. If you want to get online and surf the internet safely and with speed then you're going to have to bump up your budget to at least $299. Ebay and some other computer auctions are the only places I can think of where you could find 200 dollar laptop computers. Keep in mind that $200 laptops are old, used, outdated computers that typically contain discontinued components.
There are new desktop computers on the market that start at $199 and are more than suitable for surfing the internet safely, receiving and sending email, listening to and burning CDs, watching DVDs, and downloading or saving a reasonable amount of files. The lowest-priced laptops usually go for $399 although Asus does produce a 7 inch model that starts at $299(only has 2 GB hard drive space). If you desire the lowest-priced PC possible and want a secure connection to the internet then I recommend checking out the options outlined further
