Thanks! I splitted that one in two:

What is Maemo 5 / Fremantle?
Fremantle is the codename of Maemo 5, which is the next major release after OS2008 / Maemo 4.1 / Diablo

Will Maemo 5 run in the Internet Tablets?
Not officially but perhaps through the Mer community project. Maemo 5 is optimized for the OMAP3 architecture, the N810 and N800 are based in OMAP2 and the 770 in OMAP1 (discussion).

Also added another one:

What is the difference between Maemo and maemo.org?
Maemo refers to the software platform developed by Nokia and maemo.org refers to the community interested in this platform and related software and devices (more).

I saw you have added text instead of letting the raw links. Surely better to give basic answers to new users (more thanks) but let's keep the texts as short and generic as possible to avoid the maintenance overhead GA was fearing above (with a good reason).

We have 8 FAQ now and a new problem starts to come: sorting.
