You might want to check it out again. They've just done a UI update, and while it's still not as simple as the iPF app was, it's better.
The website is actually pretty usable from the iPad and Safari. Far better than the old site was.
I tend to bounce between the two, depending on mood and what I'm trying to do.
That said, I am on the computer right now, and that is still my most common method of accessing the forum. It's much much easier to be my overly wordy self when I have keyboard and a huge screen.
But I don't have a puter, only my ipad, sooo?
