We have already seen some detailed videos of the HTC Hero versus the iPhone 3GS from Noah at phonedog.com. Well, a few more have appeared since then. Pocketnow.com has a similar video up, although they concentrate on the browsing experience versus the iPhone and Windows-based Samsung Omnia II.
Then we have Jon over at TechnoBuffalo, who has produced a couple of videos comparing the Hero to the iPhone 3GS. The first looks at the browser & keyboard, whilst the second compares the Application Store & YouTube. You can check out all of the videos after the jump.
