While I have no problem with sous vide'ing my meat and chicken, I am somewhat concerned with putting fish in there given I can get the fish to where I want it in the oven without worrying too much, vs chicken/meat which will always end up tough and overdone.
I don't think that's entirely correct for salmon. Yes, meats which are cooked beyond a certain time frame will see the growth of certain bacteria... but the issue with salmon is that it has a couple of different "done" points (the chart for salmon looks a bit like an "M" for optimal time/temp combos). If you cook it too long at a given target temperature, it can overshoot and get a dry or rubbery texture, even though you could cook it at a higher temperature and still it medium rare.
