A pretty positive review:

In fact, it’s a highly tactile and solid-feeling, if not weighty, device and – here’s the shocker – we really, really like it. And if it can undercut the iPad on price? Then it’s a serious contender.
We think the HP Touchpad is a superb tablet device. But better developer support is absolutely crucial, and it will live or die by its pricing.
