"Isn't Dell the only computer company that still makes computers in the US?"
No. Dell has been importing MADE IN CHINA machines for awhile now. They recently announced more lay off in support of taking more jobs over seas. Customer support is split between America and India.
Gateway has more machines built here than in china. They, Gateway, still has American built machine and all of its Customer Support is American.
I heard that one company who makes PC's is 100% built. You pay more but it is worth it to keep the jobs here. I cannot recall the name and I thought I saved in bookmarks.
