if HIV ony infects T-cells, why not let the T-Cells run out, then the virus would die out within 2 weeks b/c there are no host cells to infect, then begin a regimen to increase the t-cells again? i think that's a question.

Because it doesn't just affect t-cells, it also affects b-cells and the bodies abilities to fight infection occur in the white blood cells, among other places. Now, if HIV just hung out in the blood, maybe, just maybe you would on to something. However, the insidiousness of the disease allows it to mutate and hide in other organs. For example, an HIV+ person couldn't be an organ donor becuase of the nature of the disease. If HIV+ was a blood borne disease, then organ donation would be acceptible. I know a person who has no T-cells but continue to function. Nope, your answer is just too easy.
