"HTC has also improved the music player here (a badly needed upgrade), though like so many other applications on the phone, it feels sluggish when compared to its rivals' experiences. We had the same feeling when using the browser -- another spot where the software falls victim to the phone's underpowered hardware -- the web experience on the Hero was typically slow and frustrating."
"HTC has an explosive entry in the smartphone category with what its done on the software side... now it just needs the hardware to match."
"Going into the review, we desperately wanted to love this phone, but given the combination of a few poor hardware choices and an OS which outclasses the device it runs on, we can only recommend that you enter at your own risk."
"So Flash is kind of a big deal on new smartphones. The iPhone doesn't have it, the Pre doesn't have it, BlackBerry devices don't have it... but the Hero does. Unfortunately, in our testing, we found the inclusion actually hurts operation of the phone more than it helps"
"Like other parts of the OS, Peep seems to be hampered by the slower CPU and limited RAM as well -- scrolling can sometimes be stuttery, and it often takes some doing to refresh its content."
"We could almost feel the 528MHz processor struggling to keep us as we paged through seven homescreens of widgets -- most accessing data in the background -- and when we took at a look at the task list, it was clear that most of our memory was being sucked up with scores of little processes."
