I've had it for a few months now, I got it back in early September. It came with 1 pitcher, and made another one right after I got it. Since then it has only grown some small tendrils with baby pitchers on the ends. They haven't turned brown, just haven't developed into a pitcher yet. It's been kind of disappointing.
I had to repot it about a week ago due to some bugs and the perhaps compacting nature of 'northwest' mix. The plant is a rooted cutting. Over the past few weeks, the stem has been getting darker and woodier, and just over the past 3 days, the lower-most leaf turned brown and died. The bugs are gone (they were probably harmless anyways), and although small, the root structure did not appear to have any mold, etc.
I water the plant about every 3-4 days. I grow the plant totally indoors, under some 75 watt equiv. CFLs that it shares with my other plants. Humidity fluctuates between 45%-70%, depending on how high I have my humidifier set. The baby pitcher on the most recent tendril starting getting a bit bigger, but then stopped, (the same thing happened on my N. Spectabilis, which has yet to pitcher, but its hardly a month old.) I can't seem to stop my N. Ventricosa to stop growing though.
Like I said, once I get my battery charged, (which should be in like, 30 mins) i'll get some photos up!
Also, to answer your question xvart, from where the roots start to the top of the plant is maybe a foot. After my last re-potting, I planted it a bit deeper as to cover up some of the woodier part of the stem.
EDIT: PHOTOS
Notice how to uppermost leaf is nowhere near as long as the bottom. I am assuming this is natural

BABY PITCHERS: The two largest ones are visible in this picture. I wish they would grow already
