I would be happy to provide one to you. Where do I submit a pull request?
By the way, one of the main reasons I bought an iPad stems from the fact that HN comments were so hard to read on my iPod Touch. And I'm a student who doesn't have a lot of money to buy every latest Apple gadget. So it is pretty important to me. ;-)

HN is a side project. And what matters most about HN is content, not formatting. So this sort of thing is two steps removed from top priority.
