I have read HN, worked about as expected. The arrows are hard to touch accurately, but I have the same complaint with any mobile device (it's HN's fault--doubly so that votes can be changed).
I just went to nytimes.com and played some video on their homepage. Worked as expected. It's tricky to do direct comparisons because many sites show different versions for the iPad (the Fire seems to get a fair amount of general "mobile" sites, but is obviously too new for dedicated "Fire" sites). ESPN falls in this category, it works better on the iPad but is also specially made for it.
