As long as you have basic tech knowledge (can be substituted for the abilitly to talk out of your rear), a horribly nasty disposition, and a complete lack of sympathy for users who just purchased a new computer only to find out that something doesn't work properly or that Gateway doesn't thoroughly test for hardware compatibility, you should be fine.
Just remember the Golden Rule for Gateway sales and tech support: If anything goes wrong, have the user contact his ISP's tech support. Bad hard drive? That's a job for the ISP. Lightning fried the modem and the user needs a new one? The ISP is happy to help. A brand new computer, straight out of the box, that can't detect the modem? Of course that's the ISP's fault! Remember, any time a user contacts you for help, you have to be a complete and total prick. The only help you are allowed to offer is to tell the user to run a system restore. Not everyone can figure out how to do it without help, but that's okay. That's why the user's ISP has its own tech support.
KDOG, you seem to be fairly knowledgeable about computers. Find a job that will actually utilize your skills, instead of taking a position that will make you the second most hated person to Gateway users and the other technical support reps they contact (Gateway tech support is first). The laundry list of complaints (both from users and other techs) is a mile long. It is rare for me to speak with a user that will ever buy a second Gateway PC.
