We may have to wait until summer to purchase a webOS slate, but it won't be summer's end -- PreCentral reports that the company has confirmed a June release date for the HP TouchPad. At the enterprise-oriented HP Summit in San Francisco, CEO Leo Apotheker finally offered the month of release, and also reportedly said that the company's full-force webOS on PC initiative will begin in a humble way -- the beta will run in a web browser, and we'll see it by the end of the year.
