I still have my iPhone 4 and when I used it regularly I only ever browsed DMCTalk via Safari. I never had a problem, honestly. The retina display made everything nicely readable and everything including images loaded just as they did on a desktop. Even at full zoom-out, tapping thread links almost always brought me to the one I wanted. Sometimes I'd have to zoom, but the outward pinch gesture doesn't really make me sleepy.
And yes, Tillsy's post reiterates what I originally posted which is why Tapatalk is NOT awesome but instead, a loud and annoying piece of crap.
