Apple has apparently shipped 3 million iPads. You'll be aware of that because you read the papers, the blogs, the press releases - and Apple is brilliant at telling everyone when it has a hit (I don't remember getting so much information when it was pushing the Newton).
No doubt it'll be telling us how many iphone 4s it has shipped before too long, too, although there won't be one in my house until it catches up with itself for the quantities it needs to make. But let's stick with the iPad for the moment.
I bought mine on the day of release, mostly because I thought it would be insanity for a tech writer not to have one to play with. I stand by that. And I like it, I really do. But I have to ask myself: what have I actually done with it so far?
I've read a book. And some comics. I've put some music on it and listened to it because I can rather than because I thought it was an essential idea. I've watched bits of a television programme, changed my mind and put them onto the television instead (TV programmes, oddly, look better on TV than on an iPad).
I've done a bit of web surfing and yes it's more comfortable to look at than the iPhone screen. And I've played some games - Angry Birds is highly recommended, for example, as one of the most addictive games in the known universe.
Then I ask myself: if I hadn't thought I could make something out of writing about this gadget, would it honestly be worth the money? Because they cost a lot.
My answer is that it needs to come down an awful lot before it really represents value. I'm confident Apple would tell me that 3 million people can't be wrong, and they might well be right in that.
But I can't help thinking, at the 3m users mark, it's still a very expensive nice-to-have rather than an essential, for either business or leisure.
