glorious Palm / HP Web OS tablets are headed our way (even if we are hearing it won't be until late summer / early fall), but you know what has been supposedly headed our way for over two months now? The HP Slate 500. Yep, HP's seemingly-abandoned Windows 7 tablet is still suffering from major delays, and according to our sources and an HP customer support rep, a "material shortage" combined with a "high volume of orders" are causing these tablets to be held up. We don't have any real details on the numbers -- although, last month we had heard they received about 9,000 orders thus far -- but we do know that our very own HP Slate, which we ordered back on November 9th, still hasn't shipped and is now slated to ship out on January 22nd. And we're definitely not the only ones still patiently waiting -- a look through the TabletPC Review forums reveals that a number of irate customers are still longing for their 8.9-inch, Atom-powered tablets -- although, many of them were offered a $100 discount in exchange for not having their tablets in time for the holidays. We've reached out to HP for further comment on this, but in the meantime, we'll be refreshing our account page and hoping our Slate finally ships out before the end of the month or, you know, at least before HP starts announcing new ones in early February.
