They both have their pros and cons. I have both iphone4 and HTC inspire that I swap out every other week or so. As for customizing, tweaking the options, etc. the HTC wins, howeveer, as for ease of use and smoothness, it's the iphone hands down. All the apps just work on the iphone, period! While on the inspire, some of the apps are just so so. Heck! My kids (8 and 10 yrs) and wife can even get around on the iphone with ease. Not so on the inspire.
