Could I get an idea from Webmasterworld users how many of their visitors are checking out their sites while using an iPhone or iPad? I seem to be getting an inordinate amount of visitors using the iPhone. Here is a sample User Agent: iPhone; U; CPU iPhone OS 4_3_3 like Mac OS X; en-us) AppleWebKit/533.17.9 (KHTML, like Gecko) Version/5.0.2 Mobile/8J2 Safari/6533.18.5
Very rough estimate (based on business with text editor and pocket calculator in last two months' edited logs): 5%. That includes other platforms; I just counted "mobile". And subtracted that silly Japanese robot that pretends to be a mobile device even though it's apparently perfectly legitimate.
