Also, dbrits: I agree that not having a menu button is a little frustrating when using non-streamlined apps, especially in the examples that you gave where the three-dot button at the bottom is unattractive and hogs a lot of space. I wouldn't blame HTC, though; Google is more culpable. The whole ICS design philosophy opposes the menu button because it is not "discoverable"--I don't really understand that one, but I have seen less seasoned smartphone users get confused by the menu button--so excluding it is just bending to Google's wishes for the future of Android. I will actually probably prefer the lack of a menu button once most apps fully transition to the ICS-style top-right menu.
That being said, I, too, find the multitask button a little ridiculous. I don't necessarily mind using it, but long-pressing Home was easy enough and half of my presses of the button are accidental by the base of my thumb. I think HTC would've been better off just having Back and Home buttons and moving the two closer to the center.
Is it just me or is vibrate really weak? Maybe that's just because the original Incredible vibrated like a chainsaw, though.
