I have no disagreement with Gruber here -- he is generally on the mark. However I think it is a short-sighted perspective. The products that are in the market today often had many months to years of incubation end evolution time on them. A mere four months ago, iOS was still overwhelmingly where it was at, and on sites of the people making the apps -- like HN -- it had the dominant mindspace. That has profoundly changed. On my Android I've noticed the pace of iterations of the top tier apps is reaching an incredible pace, as obviously what was an afterthought is starting to get equal billing to their iOS product. Gruber is unquestionably right today. In three months, or six months, I think the equation will have dramatically changed. Though it will never be about "killer apps" (where exclusivity is the definition). That antiquated notion has no place in modern computing. Note that Google makes all of their "killer apps" available on iOS as well, which is exactly how it should be. In an ideal every top tier app exists on multiple platforms.
