If your device has a 5-inch screen and no phone, it's not a tablet, it's a PDA. Accept it.

Lets get something straight here: Giving a device the label 'tablet' implies a few things...

1. I'm going to ingest it
2. I'm going to dissolve it in something
3. I'm going to write on it (like paper)
4. I'm going to read from it (like paper)

While your companys 5-inch, no-phone-having device may be amazing, it's not a tablet. It's a Personal Digital Assistant. 'But it's so much more..', no it isn't. It's a palm pilot in 2010. A tablet would be something like, for instance, the iPad, or the JuJu. There are special purpose tablets, like the WACOM drawing tablets... I'd almost call that a drawing 'pad', but I think tablet works there.

THIS (DELL Streak),on the other hand... NOT A TABLET, it's dinky, it fits in your pocket, you technically can read and write on it, but it's not a tablet... it's a PDA, and a mighty bad-ass PDA at that.

I'm officially putting a 7-inch minimum on screen size to be considered a tablet.
