The gang over at PreCentral showed up to today’s HP media event several hours early just to… you know, get a good seat. While roaming the halls, the folks from HP just happen to be rehearsing this afternoon’s presentation — and the folks from PreCentral just happen to overhear several details about what we’re in store for. We now know the name of the device, the TouchPad; it’s weight, 1.5 pounds; and it’s depth, 13mm. The event kicks off at 1:00PM ET today, we’ll be there live-blogging the event to bring you the news as it happens.
