EDIT: Actually, maybe I'm just a good shopper but the only piece of tech that I've bought in the last decade that I thought was truly a piece of shit was an X-Box 360.
They really don't break that often (well maybe except the X-Box, I know many that say they are on their 4th or 5th machines). It's just the old truism that when they do people bitch and moan to 50 people and when they don't they just happily carry on without stating their Toshiba laptop is working fine today.
As I said an engineer call you'd get from a PC manufacturer on their standard 1 year warranty is $100+ down the drain if you include the cost of the call centre, the part, the logistics etc. It doesn't take much to realise that if they sell these things for $300-400 at entry level and a 10 - 20% profit margin a high failure rate would make them bankrupt within months (X-Box will survive as consoles are sold as loss leaders anyway and they make money from the games).
I know because it used to be my job to record the numbers and track they weren't increasing that on average 5% of computers we made would have a hardware failure over the usual 3 year warranty period. Now that's just one example (the PC and laptop market that I know about) but looking at that type of number and if you had repeat failures you've been very unlucky indeed.
Even while I had a little moan about my iPod being a bit buggy, it does work.
