At the webOS event that HP held today, a trio of webOS devices was announced and it shows there’s much life left yet in the relatively undeveloped operating system. HP showed off two smartphones and one tablet that ran on the webOS operating system and had support for the HP Touchstone (a wireless induction battery charging dock from HP). The new webOS devices were also designed to work with each other, taking a cue from BlackBerry’s PlayBook, though I doubt it’s going to be mandatory for TouchPad users to own another webOS device in order to fully utilize the tablet. The three devices all featured powerful web browsers with support for Adobe Flash, so it looks like Adobe has another platform backing their multimedia format. The Pre 3, Veer and TouchPad were covered in detail over at our sister site Ubergizmo, so head there for more details.
