While I don't think Nokia ever issued a press release declaring that with Maemo 5, they'd be dropping the "Internet Tablet" name, the Nokia folks at OSiM and the Summit were quite open about the change. In fact, comments to the effect of, "Ha, you're going to have to change the name of your site," were practically the greetings they used with both Thoughtfix and Reggie.

Apparently, "Internet Tablet" is too limiting a moniker for what Nokia will be doing with Maemo down the line. That, and it seemed to be considered a bit geeky sounding.

If you go back and look through threads containing posts from the first day of OSiM 2008, you'll likely find discussion of this topic. That the N810 WiMAX Edition would be the last "Internet Tablet" was about the first bit of info we learned.
