With HP’s 9.7 inch webOS 3.0 tablet well on its way and ready for the July 1st debut, it’s time to check out the other slate from HP. The mystery 7 inch model codenamed Opal might come in August, according to reports from CENS.com, a Taiwanese Economics website. The source used the info from Inventec, a manufacturer of PC taking orders from HP.

Inventec has taken orders both for 400k Touchpad units and a mystery 7 inch model, coming two months from now. No other details were revealed, but it’s very likely that HP will give us a smaller version of the TouchPad, just like Samsung is doing with the Galaxy Tab 8.9 unit versus the Galaxy Tab 10.1 Some people find it difficult to carry a 9.7 or 10 incher with them and the 7 incher is always more comfortable to use.

Will they also add a stylus in the mix and some cool software to rival HTC Flyer’s Scribe? I guess we’ll have to wait and see…
