Way back in August of last year, when temperatures were above zero and Honeycomb was still a great unknown, HP promised us the first webOS tablet will come "in early 2011." Just yesterday, however, our noteworthy exposure of the vanguard members of the webOS tablet family led us to believe that at least one of them, the Opal, would take until September to arrive. That may still be the case, but DigiTimes is bringing us back around to HP's original pledge, with word that Inventec has received instructions from HP to start producing and shipping a webOS slate (most probably the Topaz) in March. As usual, this comes from the (in)famous insider sources that tend to miss as often as they hit, but it does make sense for HP to follow up its February event with a relatively rapid product rollout.
