It's not cost effective to build the computers there, and ship them here. By the time that they arrived (6 month+ turnaround on goods shipped from the FarEast), they'd be out of date. That, and inventory prices would absolutely kill them. Most of the Dell factories that I've seen work on less than a 72 hour parts float - that knowledge is old, it may be less than that now.
All of the Dell Stuff that I put in, in America, is made in America as far as I know. I just put in some equipment in the UK, and it was manufactured in Ireland.
that's correct -- there's a huge growth happening out there and Dell wants to sell more comps in India (And china)
