Well, I'm not an A+ folk, but I have occasionally thought about becoming one, but - aside from the fairly high cost, even with a voucher - when they stopped being perpetual (take it once and it's good for life), that kind of turned me off, because I don't really want to have to retest or do continuing education or whatever once every two years to keep it current.
However, if I had good reason to (a job requires it, for instance), I would get it no problem.
