According to a Wal-Mart listing, the 32GB HP TouchPad will be priced at $599 in the US. The TouchStone induction charger stand will be priced at $80, a WebOS BT keyboard at $70 and the official case at $50.
This price point is right in line with the iPad, but significantly higher than Android. The lower price (and somewhat higher specs) on an Android tablet compared to the iPad makes sense because the software is inferior (both OS and app selection), but with the TouchPad running WebOS it will be even lower on the scale for software, at least app selection. WebOS has been quite the failure so far (or rather, quite the lack of a success, to be diplomatic) so I wouldn’t expect long queues on the release day in June.
