I've had this machine now for about 6 weeks and it was beginning to misbehave with Vista (surely the Devil's own invention) - A good example being it deleting all my saved system restore points. I lost patience and downgraded (I don't think so!) to XP Pro - This is usually a process fraught with danger but with Toshiba it was a breeze - All is now sweetness and light and I am a happy man again! It is a very quick machine, easily finds wireless networks and is a joy to type on. A plague on Vista!!
