Time For A New Computer?

I've had my computer now for about 3 years and I'm thinking of getting a new one. In day's gone by I would only purchase Gateway's but this one is a Dell and I really like it. I haven't had any of the issues with it that I used to have with the other one that kept me on the tech phone line all the time at all hours of the day, and getting additional Dell Memory is easy. One of the things I used to say I liked about the other company was that their help line was so good... now I know that it's better to never have to use it, although I hear Dell has a very good help line too. Mine has pretty much been like the Maytag's in their commercials, their repairmen must get really bored if they're all like this.
