Two names that make me shudder with horror...if I remember correctly, both companies were really all about selling cheap, nasty kit but making large amounts of money on warranties. No offence meant if you worked for Time :)
Time & Tiny were the same company in the end, as Time bought the Tiny name in 2002.
Essentially the PCs were built as cheaply as possible, that involved buying the cheapest parts and employing the cheapest workers.
Using the premise that if you pay peanuts you get monkeys, the PCs were very shoddily assembled, on a number of occasions we had PCs leave before they'd had the operating systems ghosted, or without internal components properly connected.
The two years I spent there were not the most fulfilling years of my life, but I did enjoy working there as my particular job role allowed me a certain amount of freedom to wander the premises and experience departments. Because of my wanderings I found the place to be an administrative nightmare, which probably added more to operating costs than anything else
