HP today took the wraps off a new line of all-in-one desktop PCs, running Windows 8, kicking off with the 23.6in Spectre One. Its the first for HP in its newly-renamed Spectre line of PCs after the company announced in July it would ditch the Omni branding. The new line of Spectre AIOs joins the Envy and Pavilion AIO lines, which today also added new members to the family, and follows from the Spectre range of laptops.
