Whether you've just bought a brand new computer or are looking to get a bit more use out of your existing machine, it is well worth thinking about purchasing computer peripherals. If you intend to do a lot of writing, you may want to get a Microsoft ergonomic keyboard and mouse to facilitate the process. A Logitech wireless keyboard and mouse would be perfect for those looking to get rid of unsightly wires.
If you want to play games on your computer, you could chose a Razer Naga mouse and a new sound system, such as set of Akai speakers which will really enhance the gaming experience. Another great computer peripheral is a webcam of some sort. Depending on your budget, you could go for a Trust Spotlight webcam or, for an HD experience, the Creative Labs Live! InPerson HD may be exactly what you require.
