My point was that web applications would typically have access to more data per default, in a world with no native apps with all your applications in "the cloud" more of your data would likely also be in the hands of others. I don't think they are orthogonal concerns at all.
Regarding the Coding horror link here though, I do agree with the point about native applications that essentially are repackaged web pages.
Ah, I took your point to be completely the opposite! Oops.
Whether it's a native app or "in the cloud", I think most people want their data to be synched across devices, so you're going to have to trust somebody with it.
(Well, unless you're synching encrypted data, but maybe what we should all be doing, but I wouldn't hold my breath...)
