Engadget’s Nilay Patel has an apparent scoop: pictures and details on HP’s plans for tablets based on its WebOS operating system. The images aren’t as exciting as the factoids–all tablets look pretty snazzy in product shots–but the most striking factoid is the apparent possibility that the tablets won’t ship until September. That seems eons away given how many other tablets are set to ship in the next few months. It’s also not the “early 2011″ that HP was promising a few months ago. And if HP talks about the tablets at its Feburary 9th WebOS event, it would be preannouncing them by seven months or so. Here’s hoping we don’t have the whole story just yet–and that the whole story involves WebOS tablets showing up before the fall.
