I'm actually posting this from my Triumph. I've been rocken them since they released. What exactly do you mean by, "What could take advantage of its power"?
The first thing I would do is root it, which I've seen you've already done, so its time to throw clockwork recovery on it. After that I recommend installing a different rom. Personally for this exact phone I use cm 7.2 g60.
Once you have flashed that season with apps to taste.
Network Spoofer, USB cleaver, penetrate pro, shark, droidsheep, wifikill, nmap, and ant if you can get it.
Those are all the "fun" apps I use, whatelse are you looking to do with your triumph?
