Well, this changes things. Right after it came out, Matt called the HTC Hero "tragically flawed." Why? Because the otherwise fantastic Sense UI was slooooow. HTC, presumably run by competent, rational human beings, has fixed this.
From the review in July:
The Hero is flawed, though, in ways that are truly depressing in light of its potential and how much it does get truly right: It's often sluggish, which absolutely destroys the user experience. It's a particularly unfortunate affliction as the iPhone 3GS and Palm Pre emphasise speed, making the Hero feel that much slower.
This was all but a dealbreaker, this frustrating slowness. But! Paul at MoDaCo has a preview of HTC's forthcoming update, which was vaguely announced yesterday, without much mention of what it would actually do. Now we know: It's about speed. And as someone who's been using a Hero for a few weeks now, this video makes my fingers tingle, ever so slightly.
