I use Windows 98 on my personal computer that has all my fun games and webpage files on it, and it works great except for it's annoying tendency to decide to reboot itself ever few hours. On the computer we use to do billing for our small little company, I run NT, and it worked a whole lot better than 98 until it ate itself taking an entire years worth of invoices with it. Thank god for hard copies....we coulda been in some deep *&^%.
