We'd made it this far without any solid confirmation, but now the night before the big Apple launch, one of Apple's partners has gone and let the cat out of the tablet-shaped bag live on TV.
Terry McGraw, CEO of McGraw-Hill publishers, was live on CNBC discussing the company's earlier earnings call, when he let the big news slip.
Asked at the end of the interview about the rumoured tablet launch, McGraw ditched the normal dodging tactics and went full steam ahead, confirming the tablet's existence, that his company has worked closely with Apple in providing ebook content for it, and the fact it will run an iPhone-based OS.
"Yeah, very exciting. Yes, they'll make their announcement tomorrow on this one," he said, seemingly unaware of the size of the beans he was spilling.
"We have worked with Apple for quite a while. And the Tablet is going to be based on the iPhone operating system and so it will be transferable. So what you are going to be able to do now – we have a consortium of e-books. And we have 95% of all our materials that are in e-book format on that one. So now with the Tablet you're going to open up the higher education market, the professional market. The Tablet is going to be just really terrific."

It seems like this is probably as solid a confirmation as we’re going to get until we hear it from the mouth of Steve Jobs himself at 6pm GMT tomorrow, so make sure you’re locked to Stuff.tv to find out all the deets as they happen.
