"In the end, there can be only one".
With the way the PC market is going, it looks like Dell will be the only major assembler left standing when it comes to purchasing personal machines. Since America is an "economic democracy" (as compared to a republic form of government), consumers vote with their dollars, and Dell just keeps raking in the cash. Like Wal-Mart, they sell for less than the competition, which keeps customers coming back for repeat sales.
Personally, the best customer support I ever got came from Gateway back in 1996. When I used Dell's support 2 years ago, I had to threaten the dcrone with the fact that I was an employee and could track him down to get him to perform his duties better.
