About the Authors
Mike Judd
Keith Brindley
Keith is a freelance journalist whose whole life (well, apart from the wife, the kids, the music and the mountain bike) is computers. He's been writing about them (computers, that is) for over 18 years, in the meantime working as a teacher, lecturer, engineer, journalist and finally (for the last 12 years) freelance in the computing field. He fondly remembers his first contacts with the Commodore Pet, the various Sinclair oddities, the BBC, PC-DOS, MS-DOS, the Mac, and the various incarnations of Windows. He dreams of new software and hardware, he realises that writing about computers makes little compared to making computers or writing the software for them, he is fully committed to passing his experience along to and making computer-life easier for his readers, yet still enjoys what he's doing. Which can't be all bad!
