The hacks interest me, but not enough to actually put up with the risk and potential frustration of having to stay up-to-date with each day's new developments and potential issues. I just don't have the patience for it. I don't want to have to think about my phone that much. I guess it doesn't help (or hurt) that I haven't yet seen a "killer app" that tempts me into hacking my phone. I sure have no interest in hacking it just so that it's hacked.
If a really cool app comes along that I think I'd really appreciate using then I'll reconsider, but for now the "because it's there" motivation isn't compelling enough to put up with the frustrations.
