Yes please compare apples to apples. Claiming that iPhone did not support something for only a year is BS because thats how it launched. what about multi-tasking? Oh iPhone didn't support that for a couple of years only.
GRANTED that iPhone is first-to-market and actually created the market, so they get the brownie points because there was nothing even close available. Now if you want to compete with the iPhone to any extent you MUST compete with the iPhone of today, not the iPhone of 1G.
Do you know what browser the Kin has? It doesn't seem unlikely that the Kin would support web apps.
