No complaints hee
Seems whoever you're hardware supplier is, sometimes you'll have a bad run of luck. Our company has had precisely two hardware problems I'm aware of with Dell laptops in two years (that weren't user-generated - thanks for fixing my keyboard under warranty, Dell guy). That's in about five years of exclusively buying Dell.
My D830, keyboard-knack aside, hasn't had a problem in the 18 months or so I've had it, and the Inspiron it replaced really took some abuse, what with having demonstration versions of Domino, Websphere Portal and WAS, and DB2, plus some desktop apps all running at the same time. In half a gig of memory.
But then my registry's pretty clean, no SE Asian shopping mall software, and there's no games on it.
I take the point that if there's dodgy components, there's dodgy components, but I really can't see that any major manufacturer is going to be more immune from that than another.
