Previously I have written about alternatives to Internet Explorer and alternatives to Windows Messenger. This time it's alternatives to the Adobe Reader.
Foxit Reader is a small and fast PDF reader. It is commercial software but the basic version is free and has all the main features and, in some aspeceven more than Adobe Reader has.
Sumatra PDF is another slim and quick reader. It is designed so that it does not require any special installation procedures and can be used from a USB stick. It is also open source, if that's what you prefer.
Both of these are good alternatives to the Adobe Reader, so it's a personal choice between them. Either one works faster than the Adobe Reader, and the software that you are using on your netbook can never be too fast.
