So you've had what 6 or 7 Dell machines at the most and that qualifies you to say they are crap. Firstly if they were that crap you would have stopped buying them after the first one or two purchases. And you haven't defined 'shoddy' or 'completely rubbish' although I don't think anyone's going to value your opinion enough to ask you to explain.
For the record, I have shifted about £50k - £60k worth of Dell equipment in the last 8 - 10 months comprising laptops, printers, servers, monitors, switches and probably more, and haven't had one single failure in any part of any machine. Not big compared to some companies obviously but I've a fair idea of the build quality of their stuff. And if I did I would know about it because I'm responsible for ongoing maintenance of most of the stuff, it's not stuff I sell and run away from.
It's perfectly fine to make your point obviously but it's silly seeing threads branding suppliers & manufacturers 'stupid' or 'rubbish.' If they were that bad they wouldn't be in business.
